As Roger mentioned discretely in his email there is much a foot with UK Govt ref open source (although i cant claim to be aware of all activities), to start you may want to check out the following....
http://www.govtalk.gov.uk/rfc/rfc_document.asp?docnum=429 a 'consultation' on open source, you are invited to respond...
However there is also http://www.vnunet.com/News/1128177
this is a major development and a step in the right direction. currently one of the main areas for open source potential for Govt is with Public Key Infrastructure (PKI), the proprietary cost of implementing this by 2005 dwarfs the NHS deal (Verisign current charge $20-30 per user for a certificate * online population of the UK :-)

(With everyone already having at least 3 unique numbers assigned to them, one of which has no US analogue.) -- Mark Evans St. Peter's CofE High School Phone: +44 1392 204764 X109 Fax: +44 1392 204763
