Hamza Extradition Delayed

The US wants to extradite Abu Hamza in order to try him there on terror charges. Those charges include supporting Al Qaeda and helping to organise kidnappings in Yemen. However, since Hamza is appealing against his convictions here in the UK the extradition hearing has been postponed. And the appeal hearing itself was postponed until December 6.

What does one trial have to do with the other? If he is cleared of all offences in the UK does that stop him being extradited to the US? The only thing that might happen as a result of this is that he is cleared in the UK and then leaves for Pakistan or some other country from where he cannot be extradited.
