Former British SAS officer claims he gave Mountbatten security warning weeks before IRA bombing

Former SAS British army corporal, Graham Yuill, was tasked with carrying out a security audit on Lord Louis Mountbatten at his Mullaghmore residence just weeks before he was murdered in an IRA bombing attack in 1979. Yuill claims he warned his superiors of a specific security risk on Mountbatten’s boat in the local harbour, but his warnings weren’t acted on
