Right Time To Stop
The Times cartoonist Peter Brookes has the funniest and most accurate take on the 'Plebgate' affair - for some reason Andrew Mitchell couldn't resist pursing the whole affair to the courts which was always a very high-risk 'winner takes all' strategy.
Up till that point the MP had enjoyed a considerable degree of public support because of the way in which details of the original incident were leaked to the media by serving officers of the Metropolitan Police and then cynically exploited by the Police Federation, the police trade union.
As ever with these issues, wisdom comes in knowing when is the right time to stop and walk away with your integrity still intact.
