Britain's Prime Minister David Cameron says British troops could start coming home from Afghanistan as early as next year.
Mr Cameron is in Afghanistan on an unannounced visit to assess the situation on the ground.
The BBC reports he says progress against the Taliban and in training Afghan military and police make him optimistic about the prospects for the first withdrawals.
Last month, Mr Cameron made a commitment to MPs to withdraw British combat troops from Afghanistan by 2015.
Britain has more than 10,000 troops deployed in Afghanistan.
