Queen and Martin McGuinness to shake hands
The Queen is due to shake hands with Northern Ireland Deputy First Minister Martin McGuinness, a former IRA commander, at an arts event in Belfast.
The event has been organised by charity Co-Operation Ireland, which works to bring divided communities together.
Its chief executive, Peter Sheridan, said the handshake would be hugely significant and people would realise "we are in life beyond conflict".
The Queen and the Duke of Edinburgh are on a two-day visit to Northern Ireland.
