'The oldest survivor of the First World War, Henry Allingham, is celebrating his 113th birthday with a party organised by the Royal Navy. The veteran soldier also holds the record as the last survivor of the Battle of Jutland, the last surviving member of the Royal Naval Air Service and the last surviving founding member of the Royal Air Force. The Royal Navy and the RAF take it in turns to host Mr Allingham's party and this year it is being held at HMS President, a building overlooking the River Thames, near London's Tower Bridge'.
