The Government has insisted that Britain, and not America, will decide when British forces pull out of Iraq. Prime Minister Gordon Brown said that troops still had 'an important job to do,' but the Liberal Democrat leader Sir Menzies Campbell criticised Brown's reluctance to give a timetable for withdrawal. He warned that the number of casualties had become unacceptable. A leading Iraqi official in Basra has warned he did not have enough troops to compensate for the loss of British forces, and has said it would take "at least two army divisions" to fill the gap.
