I want to pick up on a particular area of concern that I raised this morning. When you gave evidence to the Transport Committee, you talked about the risk of losing expertise in security. In your evidence today, you have referred to potential secondments, rather than total transfers of staff. Does that happen anywhere else in the civil service in relation to other bodies? Do people ever remain employed by the civil service while being managed by another body, with the cost head then going to that other body, too?
