Transport Secretary Louise Haigh has admitted pleading guilty to a criminal offence relating to a police investigation over a mobile phone she claimed was stolen.
In a statement, Haigh said she told police she had lost her phone during a mugging on a night out in 2013 but later found it had not been taken.
She said it was a "genuine mistake" but had been advised by a lawyer "not to comment" during a police interview. The police then referred the case to the Crown Prosecution Service, she said.
She said she pleaded guilty to making a false report to police at magistrates' court six months before becoming an MP in the 2015 election, and received a discharge - the "lowest possible outcome".
