Downing Street says no investigation will be carried out into the conduct of Chief Whip Andrew Mitchell.
It follows a letter requesting such an investigation from Yvette Cooper, the MP for Normanton, Pontefract and Castleford.
There were calls for Andrew Mitchell to resign after shouting at police officers when they refused to let him take his bicycle through the main gates at Downing Street. He has since apologised for his behaviour, but denies reports he called them "plebs".
The Secretary of the Cabinet, Sir Jeremy Heywood, has responded saying:
– Sir Jeremy Heywood, Cabinet Secretary
In light of the apology given, and also the fact that the officer concerned has accepted the apology and does not want to pursue the matter further, the Metropolitan Police Commissioner reiterated that no further action would be taken.
Given these circumstances neither the Prime Minister nor I see any purpose in a further investigation. The Prime Minister has already made clear that he regards Andrew Mitchell's behaviour on this occasion as falling well short of the standards expected of members of the Government.
