He's not 'in government'. He's a backbench MP and Labour rebel. He's an enemy of Blair.
He's always been a outspoken supporter of Saddam - that's what I meant by old news.
Generally speaking, before a democratically elected member of parliament loses his seat, he has to be found guilty of a crime that would make his position untenable, or at least proven to be involved in a scandal that would have the same effect. I think that's the proper way to proceed. If he's proven guilty of fraud (which is the allegation - via his charity dealings), then fair enough. But until that time, however much I might dislike him, it would be undemocratic to do otherwise.
