Controversy erupted in September when the Government's Chief Whip Andrew Mitchell swore at two police officers in Downing Street after they refused to open the main gate forcing him to dismount from his bicycle.
It was also claimed that he had branded the officers "plebs" warning them that they did not run the Government.
Mr Mitchell admitted swearing at the police officers, but despite resigning from his job, persistently denied ever having used the word "plebs".
But speaking on BBC Radio Five Live, Mr Hogan-Howe today insisted he was "100 per cent" behind the officers' account saying they had "no reason to lie".
He told Victoria Derbyshire: "I am 100 per cent behind the officers. They accurately reported what happened."
