The conviction of a Royal Marine for murdering an injured Afghan insurgent should not "besmirch" the organisation, Prime Minister David Cameron has said.
Speaking to marines at Downing Street, Mr Cameron said the "appalling" case in no way represented the spirit and proud history of the Royal Marines.
The sergeant, identified only as Marine A, was convicted over the shooting of the unknown man in 2011 on Friday.
