I have asked the chief executive of the Central Office of Information to write to the hon. Member.
Letter from Mark Lund, dated 27 January 2010:
As Chief Executive of the Central Office of Information (COI), I have been asked to reply to your Parliamentary Question  regarding Government Websites.
As of 31 December 2009, Departments have reported through their Website Reviews that they are operating 1,700 websites minus the 907 they have closed, i.e. 793. Of these, 182 are run by Departments and 611 by Executive Agencies and NDPBs. No central record is held that distinguishes between Executive Agencies and NDPBs.
