Agree with Richard there. A motion like this is just an expression of opinion by whatever MPs stuck around and voted for it. It's got no effect on the legal situation.

It is of course absurd that this extradition should go ahead. Any offence involved would have been committed on British soil by a British citizen, and the British authorities have decided there are no grounds for a prosecution in Britain.

It's a bit as if the Saudis were getting a Londoner deported to face trial in Rabat for having an alcoholic drink in a pub.
