Nick Clegg has become the latest Cabinet minister forced to defend Sutton Coldfield MP Andrew Mitchell over his outburst at Downing Street police.
Mr Mitchell has denied calling police officers "plebs" after they refused to let him cycle through the main gates at Downing Street on September 19th.
The senior Tory has conceded that he swore and did not show enough respect, and has apologised to the police officer involved, who accepted his apology.
Mr Clegg said:
"The Chief Whip has made it quite clear that he acknowledges what he did was wrong, he has apologised to the police officer in question, the police officer has accepted his apology."
The Deputy Prime Minister, who joked that "I know a thing or two about apologies, musical or otherwise", added: "I hope we can move on from there."
