Both the Prime Minister and the Mayor of London have backed the Metropolitan Police chief after former Chief Whip Andrew Mitchell said he had "no confidence" in Bernard Hogan-Howe.
The Evening Standard quotes a Downing Street spokesperson as saying that, "the Prime Minister has full confidence in the Metropolitan police commissioner and believes the police should be allowed to carry out the investigation."
Boris Johnson's office is also quoted as supporting Mr Hogan-Howe, "The Mayor has absolute confidence in the commissioner."
Britain's most senior police officer has promised a "ruthless" investigation into an alleged conspiracy against Andrew Mitchell.
Andrew Mitchell has written a piece in which he has accused the police of trying to destroy his career in a smear campaign.
