There has been speculation that Britain would withdraw its troops next year and Australia could be asked to increase its commitment.

Mr Howard has held talks with the Defence Minister John Reid in London, and he says he does not think Australia needs to boost the number of soldiers in Iraq.

"Our position is that we've provided additional forces," he said.

"We admire the work the British have done, the southern part of Iraq has been the area of British operation, we're working together and we have to make sure there is no premature withdrawal because that would result in victory for those who don't deserve victory," he said.
