Louise Haigh has resigned as transport secretary after it emerged she pleaded guilty to a fraud offence a decade ago.
She has admitted telling police in 2013 she had lost her work mobile phone in a mugging, but later found it had not been taken.
She was given a conditional discharge by magistrates, following the incident which happened before she became an MP.
Haigh’s is the first resignation from Sir Keir Starmer’s government and the 37-year-old said her appointment as the “youngest ever” female cabinet minister “remains one of the proudest achievements of my life”.
However, it raises questions over the prime minister’s judgement in appointing someone with a spent conviction to his cabinet, having previously attacked the Conservatives during Partygate, saying “lawbreakers can’t be lawmakers”.
At the time of the offence, Haigh was working as a public policy manager for insurance company Aviva.
Following reports by Sky and The Times on Thursday, Haigh issued a statement, saying she reported a “terrifying” mugging in London to police.
She said she reported the phone as one of a number of items she believed had been stolen, and was issued with a new work phone.
Some time later, she added, she had discovered the handset was still in her house and she switched it on, which “triggered police attention” leading to her being called in for questioning.
“My solicitor advised me not to comment during that interview and I regret following that advice,” she said. The matter was sent to magistrates.
Haigh said she pleaded guilty to making a false report to police at a magistrates’ court, six months before becoming an MP in the 2015 general election, and received a discharge – the “lowest possible outcome”.
She added: “Under the advice of my solicitor I pleaded guilty – despite the fact this was a genuine mistake from which I did not make any gain.”
But The Times claims this row relates to more than one mobile phone being stolen or going missing.
Haigh’s team have not denied this but have not been drawn on it either.
On Friday, Haigh sent a resignation letter to Sir Keir, saying she did not want to become a distraction and Labour would be “best served by my supporting you from outside government”.
In response, Sir Keir said Haigh had made “huge strides” as transport secretary to take the rail system back into public ownership, and thanked her for her work.
Whitehall sources told the BBC the transport secretary declared her discharge on appointment to the shadow cabinet in 2020, when the Labour Party was in opposition.
Some are questioning why Sir Keir gave her the job when it appears he had been informed of the specifics of this case when Haigh joined his shadow cabinet.
Haigh was responsible for one of the government’s flagship policies, the re-nationalisation of the country’s rail network under Great British Rail.
However, she was also the first cabinet minister the PM publicly rebuked, over remarks about P&O Ferries last month.
Haigh described P&O Ferries as a “rogue operator” and urged people to boycott the company, sparking a row with the ferry company’s parent operation DP World.
When it threatened to boycott a major investment summit in response, Sir Keir said Haigh’s comments were “not the view of the government”.
Left-winger
One senior Labour figure described it as a “good resignation”, which might allow her to come back at a later date with a clean slate.
While Haigh spoke in her resignation letter of “our political project,” she and the prime minister were not always on the same page politically.
She was seen as one of the few left-wing ministers in his cabinet, after serving as a shadow minister throughout Jeremy Corbyn’s Labour leadership.
A new transport secretary is likely to be announced today.
Born in 1987 in Sheffield, Haigh studied politics at Nottingham University and law at Birkbeck, University of London.
She worked as a shop steward for the union Unite and as a Metropolitan Police officer in London’s Lambeth borough before entering politics.
She has been the MP for Sheffield Heeley since 2015, and held a number of shadow ministerial and shadow cabinet roles before becoming transport secretary when Labour won the election nearly five months ago.
Candidates are disqualified from standing to be an MP only if they receive a conviction with a jail sentence of more than one year.
If a sitting MP is sentenced to a year or more imprisonment, they are automatically kicked out of the seat under the Representation of the People act 1981.
A Conservative Party spokesman said: “Louise Haigh has done the right thing in resigning. It is clear she has failed to behave to the standards expected of an MP.
“In her resignation letter, she states that Keir Starmer was already aware of the fraud conviction, which raises questions as to why the Prime Minister appointed Ms Haigh to Cabinet with responsibility for a £30bn budget?
“The onus is now on Keir Starmer to explain this obvious failure of judgement to the British public.”
