THERESA May has been accused of failing to ask Donald Trump to halt extradition action against alleged computer hacker Lauri Love as MPs raised concerns he would be at high risk of suicide.

The cross-party group of 73 MPs warned there is a "great probability" Mr Love, who has Asperger syndrome, would end his own life if sent to the US to face trial over alleged cyber crimes which lawyers say could carry a sentence of up to 99 years if convicted.

The 32-year-old, who lives with his parents near Newmarket in Suffolk, is alleged to have stolen huge amounts of data from US agencies, including the Federal Reserve, the US Army, the Department of Defence, Nasa and the FBI, in a spate of online attacks in 2012 and 2013.

In their letter to Attorney General Jeremy Wright, the MPs said "eminent experts" judged Mr Love would be at "very high" risk of suicide if sent to the US for trial and urged him to pass on their concerns to his American counterparts.

Their warnings echo concerns raised in October 2016, when more than 100 MPs wrote to then-president Barack Obama calling on him to block Mr Love's extradition, stressing their "deep concern" for his safety.

Mr Love's supporters said the Prime Minister had failed to heed the warnings and raise the case with the President, despite "widespread public concern" over the potential consequences of his extradition.

Naomi Colvin, a representative of the Courage Foundation, which runs Mr Love's defence fund and support campaign, said: "To the best of my knowledge, and that of Lauri's legal team and his family, the UK Government has not made any kind of representation to Donald Trump asking for us to be able to try Lauri here instead of him being extradited to the United States.

"More than a hundred MPs signed a letter to Barack Obama last year about Lauri and I don't think the UK Government did anything to act on those concerns either."

Home Secretary Amber Rudd authorised Mr Love's extradition to the US in November 2016 and a Home Office statement said at the time that she had "carefully considered all relevant matters".

Mr Love is due to challenge his extradition in the High Court later this month and MPs said there is "significant concern" his mental and physical health would deteriorate and become unmanageable if he is sent to the US.

A copy of the letter, signed by Labour and co-operative MP Barry Sheerman, Government minister Matt Hancock - acting in his capacity as Mr Love's local MP - and Heidi Allen, was sent to Number 10 on Friday.

It said: "If Mr Love has committed a crime, he should be prosecuted and justice should be served.

"We believe that if he is extradited, there is a great probability that he will end his own life. This has been confirmed by eminent medical experts who judge Mr Love's suicide to risk to be very high."

Mr Love's case bears similarities with that of Gary McKinnon, another alleged cyber-hacker with Asperger syndrome, who eventually had his extradition blocked by Mrs May in 2012, when she was Home Secretary, after a decade-long legal battle.

A Government spokesman said: "It is for a judge to decide on extradition cases and Mr Love's appeal will be heard by the High Court later this month.

"As this is an ongoing case it would not be appropriate to comment further."
