The Tories have committed themselves to overhauling what they describe as Britain's lopsided extradition treaty with the US, just days before computer hacker Gary McKinnon hears whether his appeal to be tried in the UK is successful.
Addressing the party conference in Manchester today, shadow justice secretary Dominic Grieve said a Conservative government will re-write the treaty.
Originally designed to send terror suspects over the Atlantic, it has been used increasingly to extradite Britons accused of white collar crimes.
Grieve spoke moments before McKinnon's mother Janis Sharp delivered an impassioned plea at the conference, during which she accused the Brown government of "throwing their people to the dogs".
The 41 year-old McKinnon, who has aspergers syndrome, a form of autism, was indicted by a U.S court in November 2002, accused of hacking into over 90 U.S military computer systems from computers in the UK, an act which U.S authorities describe as the "biggest military hack of all time".
McKinnon claims to have merely been searching for evidence of UFOs, however faces a possible 60-year jail term if his extradition is successful.
Expert witnesses for McKinnon have claimed that the evidence against McKinnon relies on hearsay.
