The war in Afghanistan
As of April 2013 there are around 7,900 British troops in Afghanistan but that number is falling to 6,000 by the end of the year.
Prime Minister David Cameron promised in July 2012 that he would bring the majority of British servicemen and women home by the end of 2014. However some soldiers might stay on after that to help train Afghan forces.
Most of the troops are based in the south of the country.
The British forces are part of the Nato-led International Security Assistance Force (Nato-ISAF) mission, trying to make the country more stable.
All Nato operations are set to finish by the end of 2014, with responsibility being transferred to Afghan forces.
