The 300th member of British forces to die in the Afghan war will be named today.
The Royal Marine, from 40 Commando, died from his wounds in the Queen Elizabeth Hospital in Birmingham on Sunday morning with his family by his side.
He was injured in a blast in the Sangin district of Helmand Province in southern Afghanistan eight days earlier, the Ministry of Defence said.
Major Renny Bulmer, spokesman for 40 Commando, based in Taunton, Somerset, said: "Our thoughts are with his immediate family who were with him at the hospital. His courage and sacrifice will not be forgotten. We will remember him."
He was the 55th UK fatality this year and the seventh member of 40 Commando killed since the Royal Marines took command of the notoriously violent Sangin area in April.
Prime Minister David Cameron led tributes to the sacrifices made by the 300 British servicemen and women who have died since operations in Afghanistan began in October 2001.
