The Cabinet Office, on an annual basis, publishes a report to Parliament on the performance of Departments in replying to correspondence from Members and Peers. The report for 2007 was published on 20 March 2008, Official Report, columns 71-74WS. Information for 2008 is currently being collated and will be published as soon as it is ready. Reports for earlier years are available in the Library of the House.
The information sought in respect of letters from members of the public could be provided only at disproportionate cost, but the Department aims to respond to all correspondence within 15 working days of receipt.
