A Briton accused of hacking into top secret military computers has lost a Law Lords appeal against being extradited to stand trial in the US.
Gary McKinnon, 42, could face a life sentence if found guilty of gaining access to 97 American military and Nasa computers from his London home.
Glasgow-born Mr McKinnon admits breaking into the computers but says he was trying to find information on UFOs.
He lost his case at the High Court in 2006 before taking it to the Lords.
The US government says he committed a malicious crime - the biggest military computer hack ever.
He is accused of hacking into the computers with the intention of intimidating the US government.
Prosecutors say he altered and deleted files at a naval air station not long after the 11 September attacks in 2001, rendering critical systems inoperable.
