The US request to extradite the British hacker accused of the "biggest military hack of all time" has been granted by the UK Home Secretary John Reid.
Gary McKinnon, accused of breaking into US government computers, has been fighting extradition since his arrest in November 2002. He has told the BBC that he feels "very worried and let down by my own government".
The US, in its case for extradition, said Mr McKinnon caused more than $700,000 (Â£375,235) of damage while exploring the computer networks at various US military institutions.
Mr McKinnon has admitted that he spent almost two years exploring these networks but said he was motivated by a search for "suppressed technology". His family have 14 days to appeal against the ruling.
