The former deputy whip, the Conservative MP Michael Fabricant, who has been a critic of Andrew Mitchell has revealed he spoke "frankly" with him yesterday:
I spoke to Andrew yesterday about this and I was frank.
This has been playing out like a long Greek tragedy and I hope that now he will take a break and rebuild his strength.
He is a very able individual and I am sure he will return to public life in due course.
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.
