The US government rejected former prime minister Gordon Brown's request for self-confessed hacker Gary McKinnon to serve a sentence in the UK, according to cables revealed by Wikileaks.
The Guardian, which has had privileged access to the Wikileaks material, reported that the US ambassador in the UK, Louis Susman, wrote to US secretary of state, Hillary Clinton, reporting: "PM Brown, in a one-on-one meeting with the ambassador, proposed a deal: that McKinnon plead guilty, make a statement of contrition, but serve any sentence of incarceration in the UK. Brown cited deep public concern that McKinnon, with his medical condition, would commit suicide or suffer injury if imprisoned in a US facility."
Prime minister David Cameron also raised the McKinnon case with US president Barack Obama at their first meeting. So far the US appears to have rejected all UK approaches.
McKinnon's mother, Janis Sharp, will give evidence to the Home Affairs select committee this morning.
Former home secretary David Blunkett - who originally permitted the extradition proceedings against McKinnon to go ahead - has since changed his view. He will also give evidence to the committee.
Chaired by Keith Vaz, it is investigating the extradition treaty signed by the UK and the US in the wake of the 9/11 attacks. Critics say the treaty is lopsided in favour of the US.
The committee is also investigating the European Arrest Warrant, which allows for the speedy extradition of nationals.
