Governance of Britain

Will the Secretary of State confirm that any proposed changes to the governance of the National Audit Office will be proceeded with on a cross-party basis, so that we can ensure the integrity and absolute independence of the Comptroller and Auditor General? On the day when Sir John Bourn has announced his retirement from his post, may I thank him for 20 years' unstinting support of the Public Accounts Committee, which I think has ensured that we now have more effective oversight of public moneys than ever before in our history?
