Radical Islamist cleric Abu Hamza has been flown to America after he lost his last-ditch High Court challenge against extradition to the USA, where he is wanted on terrorism charges.
Two judges rejected a plea for the 54-year-old to remain in the UK on health grounds.
They also rejected a legal challenge from south-London computer expert Babar Ahmad, who has been held in a UK prison without trial for eight years after being accused of raising funds for terrorism. His lawyers had argued that he should be tried in the UK, rather than in the USA.
Sir John Thomas, president of the Queen's Bench Division, sitting with Mr Justice Ouseley, said they should be extradited immediately.
