The former IRA commander (left), now Stormont’s Deputy First Minister, and the Queen shake hands in front of the world’s cameras. First, Her Majesty met Mr McGuinness behind closed doors in a room within Belfast’s Lyric theatre, and then the pair shook hands again publicly outside in full view of the world’s cameras.
Prince Philip, whose uncle Lord Mountbatten was murdered by the IRA in a bomb blast in 1979, also shook hands with the former militant.
