The Conservative MP Michael Fabricant, a party vice chairman and former deputy whip, has welcomed Sir George Young's appointment as Chief Whip:
George Young is a clever choice. As Leader of the House he was innovative with the BackBench Committee and he will listen to advice.
David Cameron admits it 'became apparent' to the former Chief Whip that he could no longer do his job. So why was it not apparent to the PM?
Government Chief Whip Andrew Mitchell has resigned after swearing at police guarding Downing Street.
Losing one's temper with a police officer would be excusable in most people, but for the Tory chief whip to do means so much more.
