The rail minister has admitted using his mobile phone while driving a vintage double-decker bus through London at rush hour.
Lord Peter Hendy was behind the wheel of the old Routemaster for a charity event when he was spotted texting a friend, as first reported by the Sunday Times.
A spokesperson for Lord Hendy said: "Last month Peter Hendy used his phone while driving. He has apologised in full for this error of judgement and has contacted the police."
A source close to Lord Hendy said he would accept the sanction, which is likely to be six points on his licence and a fine.
