An officer killed in action during an operation in southern Afghanistan was a "wonderful, loving son", his family said.
Lieutenant Paul Mervis, 27 and from London - who was a platoon commander with 2nd Battalion The Rifles - died on Friday from a blast near Sangin in northern Helmand Province.
A statement from his family said: "Paul was a wonderful, loving son, brother and friend - generous and thoughtful, with an infectious sense of fun. He was passionately committed to his men - far beyond mere duty."
His death took the number of British service personnel who have died in Afghanistan since the start of operations in October 2001 to 168.
