Rebel MP George Galloway is set to appear before a Labour Party tribunal tomorrow.

He will attend a disciplinary hearing into his claims about the prime minister's conduct ahead of the war with Iraq.

The Glasgow Kelvin MP described British soldiers as "lions led by donkeys" and Tony Blair and George W Bush as "wolves".

He was subsequently suspended from his party membership by Labour in May.

He was also accused by the Telegraph newspaper of being in receipt of payments by the former Iraqi regime led by Saddam Hussein.

However the Labour investigation will not concern itself with these claims pending a libel suit against the Telegraph from Galloway.

The controversial and colourful Scotsman has become a media hate figure because of his fierce opposition to the Iraqi war.

On Wednesday he will answer questions from Labour's National Constitutional Committee, a sub-committee of the party's ruling national executive.

The NCC can then choose to censure, exonerate or expel Galloway from the party he has represented in parliament for 16 years.

His removal would anger sections on the left of Labour.

Transport and General Workers' Union general secretary Tony Woodley recently called on the party to end its "witch hunt" against Galloway.

But the MP, who has threatened to stand as an independent at the next general election if removed, has not toned down his criticisms of Blair.

After the annual party conference in Bournemouth he described the prime minister's speech as being "like a Nuremberg rally".

"In fact the leader's speech had a lot of the leader principle - the Fuhrer principle - about it," he said.
