Via the BBC : The only gunman to survive the 1980 Iranian embassy siege in London may be freed from prison and granted asylum in the UK, BBC News has learned. SAS troops ended the six-day stand-off and killed five hostage-takers – but Fowzi Nejad escaped and was jailed. His parole hearing is in the near future and in normal circumstances he would be returned to Iran if freed. But he is believed to have a genuine case for asylum as he could face execution if sent home.

Well, he could also not be given parole.
