London Mayor Boris Johnson has demanded that Deputy Prime Minister Nick Clegg gets his Cabinet colleagues out of their "posh limos" and onto public transport.
Mr Johnson was posing as a caller from Islington on the Lib Dem leader's weekly radio phone-in for LBC 97.3.
In a pre-recorded message, the Mayor said the government needed to spend more on London's transport system.
Mr Clegg insisted the coalition had "slashed" the ministerial car budget.
He added that he was about to jump on a train to go to Sheffield.
