Remembrance Sunday: Helmand's Camp Bastion to hold last big memorial

British troops based at Camp Bastion in Afghanistan are to hold their last big memorial service on Sunday before they withdraw in 2014.

The memorial around which the service will take place is due to be relocated to the UK.

Sergeant Anthony Dyer of the 9th/12th Royal Lancers told the BBC's Jonathan Beale that the service was an opportunity for serving soldiers to "mourn for those people that they've lost".
