The British are leaving

British troops will start a major withdrawal from Iraq next May under detailed plans on military disengagement to be published next month, The Observer can reveal.

The document being drawn up by the British government and the US will be presented to the Iraqi parliament in October and will spark fresh controversy over how long British troops will stay in the country. Tony Blair hopes that, despite continuing and widespread violence in Iraq, the move will show that there is progress following the conflict of 2003.

Britain has already privately informed Japan - which also has troops in Iraq - of its plans to begin withdrawing from southern Iraq in May, a move that officials in Tokyo say would make it impossible for their own 550 soldiers to remain.
