Prime Minister David Cameron today admitted that the scandal surrounding Chief Whip Andrew Mitchell has been "damaging".
Speaking in a round of TV interviews during his visit to Brazil to help promote British business, the Prime Minister said: "Of course it's been damaging, that's why it is right that he apologised and apologised profusely. This must never happen again."
He added: "But on the basis that he has apologised and the basis that the police have said they are not taking this further, I think we should let matters rest there."
