FOR IMMEDIATE RELEASE

                          COMCAST UK CABLE PARTNERS AND
                       NTL INCORPORATED ANNOUNCE AGREEMENT
                           WITH TELEWEST PLC REGARDING
                        BIRMINGHAM CABLE AND CABLE LONDON


New York, NY;  Philadelphia,  PA - August 17, 1998 - NTL  Incorporated  (NASDAQ:
NTLI;  EASDAQ:NTLI.ed)  and  Comcast UK Cable  Partners  Limited  (NASDAQ:CMCAF)
announced  today that Comcast UK and NTL have  entered  into an  agreement  (the
"Telewest Agreement") with Telewest  Communications plc ("Telewest") relating to
Comcast  UK's  ownership  interests in  Birmingham  Cable  Corporation  Limited,
Comcast UK's and Telewest's  respective  ownership interests in Cable London plc
and certain other related matters.

Pursuant  to the  Telewest  Agreement,  Comcast  UK has agreed to sell its 27.5%
ownership  interest in  Birmingham  Cable to Telewest for UK 125 million  pounds
sterling,  plus UK 5 million pounds sterling for certain  subordinated  debt and
fees owed to  Comcast  UK, and  Comcast  UK and  Telewest  have  resolved  their
differences regarding the operations of the terms of the Co-Ownership  Agreement
between them as principal  shareholders of Birmingham  Cable and the Articles of
Association of Birmingham Cable. Comcast UK and Telewest have also agreed within
a certain  time period to  rationalize  their joint  ownership  of Cable  London
pursuant to an agreed procedure. Generally between six and nine months after the
Amalgamation,  Comcast  UK (or  NTL  following  the  Amalgamation)  will  notify
Telewest of the price at which it is willing to sell its 50% ownership  interest
in Cable London to Telewest. Following such notification, Telewest at its option
will be required at that price to either  purchase  Comcast  UK's 50%  ownership
interest in Cable London or sell its 50%  ownership  interest in Cable London to
Comcast UK (or NTL).

The  arrangements  with  Telewest are not  dependent  upon the  consummation  of
Comcast UK's amalgamation (the "Amalgamation") with a wholly-owned subsidiary of
NTL.

As a result of the  Telewest  Agreement,  the status of Comcast  UK's  ownership
interest in Cable London has been resolved for purposes of the Amalgamation and,
assuming  consummation  of the  sale  of  Comcast  UK's  ownership  interest  in
Birmingham Cable to Telewest  immediately prior to the Amalgamation,  Comcast UK
shareholders will receive in the Amalgamation  0.3745 shares of NTL common stock
for each Comcast UK share.

In  connection  with the Telewest  Agreement,  Comcast UK and NTL have agreed to
extend  the  termination  date for the  Amalgamation  from  October  5,  1998 to
November 4, 1998.
