LONDON (AP) — British Transport Minister Louise Haigh resigned on Friday over a decade-old fraud conviction for claiming her cellphone had been stolen.

In a letter to Prime Minister Keir Starmer, Haigh said, “I remain totally committed to our political project, but I now believe it will be best served by my supporting you from outside government.

“I appreciate that whatever the facts of the matter, this issue will inevitably be a distraction from delivering on the work of this government and the policies to which we are both committed,” she wrote.

The resignation came hours after Sky News and The Times of London newspaper reported that Haigh had been charged with fraud after she reported that a work cellphone had been stolen after she was mugged in 2013. She later said she had mistakenly listed it among the stolen items.

After she found the phone and switched it back on, she was called in for questioning by police. Haigh pleaded guilty to fraud by misrepresentation and was given a conditional discharge.

In a statement before her resignation, Haigh said that "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. The magistrates accepted all of these arguments and gave me the lowest possible outcome (a discharge) available.”

Haigh, 37, has represented a district in Sheffield, northern England, in Parliament since 2015 and was named to the key transport post after Starmer's center-left Labour party was elected in July.

Starmer appointed Heidi Alexander, 49, as Haigh's replacement. Alexander returned to Parliament in July's general election after a 6-year absence, part of which she spent at City Hall in London with a prominent position overseeing the capital's transport system.
