I thank the right hon. Lady for what she has said. Notwithstanding the existence of strongly differing opinions on this legislation, and on the wider issue of Brexit, I hope that all colleagues will share in the appreciation for the skill and dedication of our professional staff. Colin Lee, the Clerk at the Table sitting in front of me, is well known to many throughout the House as a quite outstanding public servant, and the same is true of the whole team who serve us so well and so faithfully and dispassionately day after day. That is respected, and I appreciate the fact that it has been put on the record by the right hon. Lady.
