Addressing a crowd at the International Institute of Strategic Studies in London, Allawi spoke about a British hostage in Iraq, Kenneth Bigley. Allawi said it is "repugnant" to take an innocent man and use him as a political pawn.
While Allawi was in Britain, the governing Labour Party rejected a motion calling for the withdrawal of British troops from Iraq as soon as possible.
Labour has been deeply divided over the government's strong support for the Iraq war. Had the antiwar motion succeeded today, it would have been a major embarrassment for Prime Minister Tony Blair.
Allawi said that "calls for early withdrawal are music to the ears of terrorists and insurgents."
