Mr Truswell was a Leeds city councillor before becoming an MP
A Leeds MP who was injured in a car crash has said he will step down at the next general election because he does not have the stamina to run for office.
Paul Truswell, the Labour MP for Pudsey, is still being treated for the injuries he suffered when his car hit a post on a dual carriageway in May.
The 53-year-old former city councillor, who was elected in 1997, said he was also having to cope with a bereavement.
He added he found it "increasingly difficult" to manage his workload.
In a statement, Mr Truswell said: "We all have to deal with life's many problems, but my recent traumatic car crash... has come on top of a period when I have found it increasingly difficult to undertake my heavy workload as an MP and to cope with a succession of family and personal issues, including illness, bereavement, and caring responsibilities.
"I have reluctantly come to the conclusion that I do not, at this time, have the physical and mental stamina to fulfil both of the hugely demanding roles of MP and parliamentary candidate in the run-up to the next general election.
"Besides dealing with any ongoing health issues, I must devote my time and energy to my duties as an MP, so I am announcing now that I will stand down in order to give the Labour Party time to select a new candidate to represent Pudsey."
Jamie Hanley, chairman of Pudsey Labour Party, said Mr Truswell had been a "magnificent" MP whose work had been "outstanding".
"This news will come as a shock to Labour Party members in Pudsey, however I am sure everyone will understand Paul's reasons for retiring," he said.
