ITEM 1      SECURITY AND ISSUER

            This constitutes Amendment No. 3 (the "Amendment") to the Statement
            on Schedule 13D (the "Statement"), dated September 21, 1998, as
            amended by Amendment No. 1 thereto, dated November 12, 1998, and
            Amendment No. 2 thereto, dated August 31, 1999, with respect to the
            Ordinary Shares, par value 10 pence per share ("Telewest Ordinary
            Shares"), of Telewest Communications plc, a public limited company
            incorporated under the laws of England and Wales ("Telewest"). All
            capitalized terms used and not otherwise defined herein shall have
            the meanings assigned to these terms in the Statement.

ITEM 4      PURPOSE OF TRANSACTION

            PROPOSED RIGHTS ISSUE

            On October 4, 1999, Telewest announced that it was posting a
            circular to its shareholders (the "Circular") containing further
            details of its proposed rights issue (the "Rights Issue"), the
            proceeds of which will fund the majority of the consideration for
            Telewest's acquisition of the outstanding 50 percent interest in
            Cable London plc (the "Acquisition").

            ACQUISITION OF MEDIAONE INTEREST IN TELEWEST BY MICROSOFT

            On October 4, 1999, MediaOne entered into a Merger Agreement (the
            "Merger Agreement") with Microsoft Corporation ("Microsoft")
            pursuant to which members of the Microsoft group will acquire
            MediaOne's existing indirect interest of 638,347,122 Telewest
            Ordinary Shares by way of a merger between certain Microsoft and
            MediaOne affiliates (the "Merger"). The Merger is conditional, among
            other things, on regulatory approval, certain Telewest Ordinary
            Shares currently held by MediaOne having been redesignated as
            limited voting convertible Telewest ordinary shares of 10p each in
            the proportions set forth in the Merger Agreement (the
            "Redesignation"), Telewest shareholders approving a proposed new
            relationship agreement (which will only become effective once the
            Redesignation has been completed), and Microsoft becoming upon the
            closing of the transactions contemplated under the Merger Agreement
            the indirect beneficial owner of a percentage of Telewest Ordinary
            Shares and limited voting convertible ordinary shares of Telewest
            (on a fully diluted basis (but ignoring the issuance of Telewest
            shares upon the exercise of employee stock options) following the
            Rights Issue) that is no less than the percentage of Telewest
            Ordinary Shares and limited voting convertible ordinary shares of
            Telewest (on a fully diluted basis) beneficially owned by MediaOne
            immediately following the Rights Issue assuming for purposes of this
            condition that Microsoft has only subscribed for the number of
            Telewest Shares not taken up by MediaOne and that MediaOne has not
            disposed of any Telewest shares since the date of the Rights Issue.

            The foregoing description of the Merger Agreement is a summary
            thereof and does not purport to be complete. The full text of the
            Merger Agreement is attached hereto as Exhibit (11) and is
            incorporated herein by reference.

            UNDERTAKING

            In connection with the Rights Issue and the Merger, MediaOne UK
            Cable, Inc. ("MUKC") and MediaOne Cable Partnership Holdings Inc.
            ("MCPH") entered into an Undertaking, dated October 1999, with TW
            Holdings LLC ("TW Holdings") and Liberty UK, Inc. ("Liberty")
            addressed to Telewest (the "Undertaking"). Pursuant to the terms of
            the Undertaking, each of TW Holdings and MUKC agreed, among other
            things, (i) not to subscribe for all or any of Telewest's new
            ordinary shares of 10p each, as set forth in the Undertaking (the
            "New Ordinary Shares"), for which each (and in the case of TW
            Holdings, each of the registered holders of the shares beneficially
            owned by TW Holdings (the "Registered Holders")) is entitled to
            subscribe pursuant to the Rights Issue (the "New Shares"); (ii) not
            to (and in the case of TW Holdings, to direct the Registered Holders
            not to) renounce, or otherwise deal with, their respective rights to
            the New Shares and agreed that such rights shall not be sold in the
            market for the benefit of each of them; (iii) to vote their
            respective Telewest Ordinary Shares in favor of the resolutions set
            out in the Circular and to waive all and any rights (including,
            without limitation, veto rights) each of them, or any director of
            Telewest appointed by each of them may have under Telewest's
            Articles of Association or under any other contractual arrangements
            in place with respect to Telewest, so far as such rights relate to
            the Rights Issue (and all matters incidental thereto); and (iv) not
            (and in the case of TW Holdings, to direct the Registered Holders
            not) at any time prior to 3:00 p.m. on the second business day after
            the latest time for acceptance and payment under the Rights Issue
            (unless in the case of MUKC or its affiliates the following is or
            relates, with Liberty's prior written consent, to the Merger): (a)
            sell, transfer, charge, encumber, grant any option over or otherwise
            dispose of any of their respective Telewest Ordinary Shares, (b)
            accept any offer in respect in respect of any of their respective
            Telewest Ordinary Shares (whether it is conditional or unconditional
            and irrespective of the means by which it is implemented), (c) enter
            into any agreement or arrangement or permit any agreement to be
            entered into or incur any obligation or permit any obligation to
            arise: (aa) to do any of the acts referred to in sub-clause (a) or
            (b) above, (bb) in relation to, or operating by reference to, the
            Telewest Ordinary Shares in which each is interested (for the
            purposes of English law); or (cc) which, in relation to the Telewest
            Ordinary Shares in which each is interested (for the purposes of
            English law) would or might restrict or impede the Acquisition or
            the Rights Issue. MUKC and MCPH also each agreed to act upon the
            directions of TW Holdings through which MUKC and MCPH indirectly
            hold a certain number of Telewest Ordinary Shares as set forth and
            in accordance with the Undertaking. In addition, MUKC and TW
            Holdings consented to the Redesignation.

            The foregoing description of the Undertaking is a summary thereof
            and does not purport to be complete. The full text of the
            Undertaking is attached hereto as Exhibit (12) and is incorporated
            herein by reference.

         be substituted therefor in order to carry out, so far as may be valid
         and enforceable, the intent and purpose of such invalid or
         unenforceable provision and (b) the remainder of this Agreement and the
         application of such provision to other persons, entities or
         circumstances shall not be affected by such invalidity or
         unenforceability, nor shall such invalidity or unenforceability affect

                  other provision (in any case whether oral, written, express or
                  implied) made, given or agreed to by any person (whether a
                  party to this Agreement or not) except those expressly set out
                  or referred to in this Agreement and the only remedy or
                  remedies available in respect of any misrepresentation or
                  untrue statement made to it shall be a claim for breach of
                  contract under this Agreement or the indemnification provided
                  for in this Agreement; and

         (b)      this clause 14.2 shall not apply to any statement,
                  representation or warranty made fraudulently or to any
                  provision of this Agreement which was induced by, or otherwise
                  entered into as a result of, fraud, for which the remedies
                  shall be all those available under the law governing this

         construed or operate as a waiver thereof, nor shall any single or
         partial exercise of any right, remedy, power or privilege preclude any
         other or further exercise thereof or the exercise of any other right,

         incorporated, the parties hereto shall amend this Agreement to cause
         each of such entities to become parties to this Agreement; provided
         that the parties hereto agree that such entity shall become parties to
         the minimum extent necessary so that the Mergers may be validly
         consummated under Article 111, Section 105 of the CBCA and any
         approvals of MOUK, MOCP and International necessary for the

                  under Sections Q.1(a) and (b) hereof, the determination of the
                  Taxes of the Companies for the portion of the year of period
                  ending on, and the portion of the year or period beginning

                  Companies and TW Holdings had a taxable year or period which
                  ended at the close of business on the Closing Date and did not
                  include any portion of the Closing Date after the time of
                  Closing except that exemption, allowances or deductions that
                  are calculated on an annual basis, such as the deduction for
                  depreciation, shall be apportioned on a time basis.

         (d)      Adjustment to Purchase Price

                  Any payment under this Section Q will be an adjustment to the

         (e)      Tax Returns

                  MediaOne shall file or cause to be filed when due all Tax
                  Returns that are required to be filed by or with respect to
                  the Companies for taxable years or periods ending on or before
                  Closing and shall pay any Taxes due in respect of such Tax
                  Returns, and Microsoft shall file or cause to be filed when
                  due all Tax Returns that are required to be filed by or with
                  respect to the Companies for taxable years or periods ending
                  after Closing and shall remit any Taxes due in respect to such
                  Tax Returns. MediaOne shall have the right to review, approve
                  and consent to the filing of any Tax Return that the Companies
                  are required to file on a single entity basis reflecting a Tax
                  for which MediaOne is liable pursuant to Section Q.1(a)
                  (taking into account the provisions of Q.1(c)) and, subject to
                  such review, approval and consent, which approval and consent
                  shall not be unreasonably withheld, MediaOne shall pay
                  Microsoft the Taxes for which MediaOne is liable pursuant to
                  Section Q.1(a) (taking into account the provisions of Section
                  Q.1(c)) but which are payable with Tax Returns to be filed by
                  Microsoft pursuant to the previous sentence within ten days
                  prior to the due date for the filing of such Tax Returns.

         (f)      Consent Provisions

                  Microsoft shall promptly notify MediaOne in writing upon
                  receipt by Microsoft, any of its affiliates or the Companies
                  of notice of any pending or threatened federal, state, local
                  or foreign income or franchise tax audits or assessments which
                  may affect the tax liabilities of the Companies for which
                  MediaOne would be required to indemnify Microsoft pursuant to
                  Section Q.1(a), provided that failure to comply with this
                  provision shall not effect Microsoft's right to
                  indemnification hereunder. MediaOne shall have the sole right
                  to represent the Companies' interests in any tax audit or
                  administrative or court proceeding relating to taxes of the
                  Companies for taxable periods ending on or before Closing, and
                  to employ counsel of its choice at its expense.
                  Notwithstanding the foregoing, MediaOne shall not be entitled
                  to settle, either administratively or after the commencement
                  of litigation, any claim for Taxes which would adversely
                  affect the liability for Taxes of Microsoft or the Companies
                  for any period after Closing to any extent (including, but not
                  limited to, the imposition of income tax deficiencies, the
                  reduction of asset basis or cost adjustments) without the
                  prior written consent of Microsoft. Such consent shall not be
                  unreasonably withheld, and shall not be necessary to the
                  extent that MediaOne has indemnified Microsoft against the
                  effects of any such settlement.


                                      -46-
<PAGE>


                  MediaOne and Microsoft shall jointly control at their
                  respective expense the defence of any claim for Taxes for a
                  year or period ending after Closing which may be the subject
                  of indemnification by MediaOne pursuant to Section Q.1(a) and,
                  with the written consent of Microsoft, and at its sole
                  expense, may assume the entire defence of such tax claim.
                  Neither Microsoft nor the Companies may agree to settle any
                  tax claim for the portion of the year or period ending on
                  Closing which may be the subject of indemnification by
                  MediaOne under Section Q.1(a) without the prior written
                  consent of MediaOne, which consent shall not be unreasonably
                  withheld.

         (g)      Termination of Tax Allocation Agreements
                  Any tax allocation or sharing agreement or arrangement,
                  whether or not written, that may have been entered into by
                  MediaOne or any member of MediaOne's Group and the Companies
                  shall be terminated as to the Companies as of Closing, and no
                  payments which are owed by or to the Companies pursuant
                  thereto shall be made thereunder.

         (h)      Refunds, etc.

                  Microsoft shall promptly transfer, or cause to be transferred,
                  to MediaOne the entire amount of any refund or overpayment
                  (including interest thereon) received or utilized by Microsoft
                  or its Affiliates of any Taxes that were paid by MediaOne or
                  its Affiliates or that may be the subject of indemnification
                  by MediaOne under Section Q.1 hereof and, at the reasonable
                  request and at the expense of MediaOne, will file or cause to
                  be filed a claim for any such refund or over-payment.
                  Microsoft shall cause the Companies to forego the carryback to
                  a period ending on or before the Closing of any net operating
                  loss, net capital loss or other deduction or credit incurred
                  by the Companies in any taxable period ending after the
                  Closing. Unless required by law or by any agreement entered
                  into by MOUK or MOCP prior to Closing, Microsoft shall not,
                  and shall not permit the Companies to, file any amended Tax
                  Return after Closing with respect to any taxable period ending
                  on or before Closing.

                  position on any U.S. federal, state, local or foreign tax
                  return, or take any other tax reporting position, that is

                  taxable period for which the other may have a liability under
                  this Section Q; and

         (e)      furnish the other with copies of all correspondence received
                  from any taxing authority in connection with any tax audit or
                  information request with respect to any such taxable period.

Q.4      Survival of Obligations

         The obligations of the parties set forth in this Section Q shall be
