The Queen's historic meeting with Sinn Fein's Martin McGuinness will be recorded for posterity, Buckingham Palace has confirmed.
The initial handshake between the Queen and the former IRA commander will remain private but farewells between the two individuals - when another handshake is expected - will be filmed and photographed.
Peter Sheridan, chief executive of the peace charity Co-operation Ireland which will host the meeting at Belfast's Lyric Theatre, said the event will be hugely significant.
Mr McGuinness, Stormont deputy First Minister, has described the upcoming greeting as a symbolic gesture of "stretching out the hand of peace and reconciliation to Queen Elizabeth who represents hundreds of thousands of unionists in the north".
