On a point of order, Mr. Deputy Speaker. Is it normal House practice for two hon. Members from the Government side to give their names to you as Tellers and to be sitting in a position ready to act as Tellers, but then to withdraw from the proceedings suddenly at a time when many hon. Members might have wanted to continue their protest about the incompetence of the Criminal Records Bureau by voting on the new clauses and new schedules, which have been the subject of only a couple of minutes' debate? Have you been told why the people who were ready to act as Tellers suddenly disappeared?
