Notifications of shareholdings in company

The partners in the Rostrum Investors limited partnerships have notified Amlin
that, following a recent share portfolio adjustment by one of the partner
investors outside the Rostrum partnership, they now have notifiable interests by
virtue of Part VI of the Companies Act 1985 in a total of 11,206,859 of Amlin's
ordinary shares of 25p each ('Shares'), representing 2.83% of Amlin's Shares in
issue. The previous such notification, announced on 10 July 2003, was of
12,945,544 Shares, which was 3.32% of Amlin's Shares in issue at that time.

Disclosures have been received in respect of these 11,206,859 Shares from the
following limited partners: Rostrum Limited, BriTel Fund Trustees Limited
('Britel'), Possfund Custodian Trustee Limited ('Possfund'), British Airways
Pension Trustees Limited ('British Airways Pensions'), Stargas Nominees Limited
('Stargas') and Kleinwort Benson (Jersey) Trustees Limited ('Kleinwort
Trustees') (the latter as a limited partner and as trustee of the Rostrum Group
Trust). Mr Michael Wade has also disclosed an interest in the same 11,206,859
Shares by reason of his effective shareholding in Rostrum Limited.

By virtue of Sections 204 and 205 of the Companies Act 1985, Britel, Possfund,
British Airways Pensions, Stargas and Kleinwort Trustees are interested in
6,821,060 (1.73% of Amlin's Shares in issue), 8,654,573 (2.19%), 11,206,859
(2.83%), 11,206,859 (2.83%) and 11,206,859 (2.83%) Shares respectively, all such
interests being over all or part of the 11,206,859 shares referred to above.

The Shares referred to in the notifications from the Rostrum Investors partners
are held as follows:

          KB (CI) Nominees Ltd                    10,297,470
          Possfund Nominees Ltd                       70,048
          BriTel Fund Nominees Ltd                   839,341
*T          

Finally, Rostrum Group Limited has confirmed that it still has an interest in
10,297,470 Shares, which are the Shares referred to above as being held by KB
(CI) Nominees Ltd. This interest is by virtue of Rostrum Group Limited being
entitled to exercise control over the voting rights conferred by such shares.
These Shares represent less than 3% of Amlin's shares in issue.

As all of these interests are now over less than 3% of Amlin's shares in issue,
no further notifications will be again required unless any of the interests
again reach 3% or more of Amlin's shares.
