Attn: Company Secretary



24 February 2005



Dear Sirs,



Enclosed are closing notifications of disclosable interests under the U.K.
Companies Act 1985.  Please note that while this information details the
disclosable interests of more than one entity, the enclosed disclosure
constitutes separate notifications of interest which have been combined solely
for purposes of clarify and efficiency.  It is not intended to indicate that any
of these entities act as a group or in concert with respect to these interests.



These disclosures are made in the interest of conformity with the Companies Act.
  The Interest detailed herein were acquired solely for investment purposes.
For disclosure purposes, holdings should be represented as FMR Corp. and its
direct and indirect subsidiaries, and Fidelity International Limited (FIL) and
its direct and indirect subsidiaries, both being non-beneficial holders.



Please be advised that no further notifications will be processed unless a
disclosable interest is obtained.  If you have any questions please contact
Kerrie Barnett on 01737 837092 or by FAX on 01737 837450.



Yours faithfully



Kerrie Barnett

Regulatory Reporting Analyst
