Radical Muslim cleric Abu Hamza al-Masri has appealed against his extradition to the US on terror charges.
Abu Hamza is serving a seven-year jail term
Abu Hamza, of west London, is wanted by the US authorities on charges which include providing support to al-Qaeda.
Home Secretary Jacqui Smith authorised the 49-year-old's extradition on 7 February and is to consider the appeal.
The Egypt-born preacher is currently serving a seven-year jail term in the UK for inciting murder and race hate.
The extradition was originally approved by a court in London in November, but the handover to US authorities had been pending the final approval of home secretary.
Abu Hamza's solicitor, Muddassar Arani, previously said the extradition "might be a popular move with some sections of the public. But we have to ask ourselves whether it is morally right".
