I have to tell the House that yesterday I received a letter from Sir Philip Mawer, Parliamentary Commissioner for Standards, informing me that he wishes to step down from the appointment on 31 December 2007. By that date, Sir Philip will have served for almost six years. He records in his letter that he counts it a great privilege to have been able to serve the House in such a worthwhile capacity. There will be an opportunity for Members to express their appreciation at a future date. I shall arrange for a copy of his letter to be placed in the Library.
