The day Martin McGuinness shook the Queen's hand
It was a handshake that lasted mere seconds, but was a moment of historic significance when Martin McGuinness and the Queen first shook hands.
Such a gesture between the former IRA commander and Her Majesty would once have been unimaginable, but at a charity event in Belfast on a Wednesday morning in June 2012 the hand of friendship was extended.
Former PA photographer Paul Faith was the only photographer allowed access to photograph the handshake.
"I feel so privileged to have witnessed that significant and historic moment,'' he said. "I remember that Martin appeared very relaxed and confident and happy to stand beside the Queen.
"The significance of it for me didn't really sink in until the next day when I saw the pictures in the papers. Every front page was carrying the photograph and it hit me that this was going to be a historic image.''
He added: "The day after the handshake I was sitting in the press room at the Irish Open and Martin McGuinness came in with Peter Robinson.
"He came over to me and shook my hand and said 'you've made me famous again'. He then asked for a photograph of him and I shaking hands.
"I also took the photograph of him and Ian Paisley that led to them being called the Chuckle Brothers.
"He later signed that photograph for me and said 'so Paul, you're the one who turned me into a Chuckle Brother. Well done'.''
The day after shaking hands with the Queen, Mr McGuinness spoke about its "momentous and historical'' significance.
He said the meeting had the potential to define "a new relationship between Britain and Ireland and between the Irish people themselves''.
In a speech in Westminster he said the handshake "was in a very pointed, deliberate and symbolic way offering the hand of friendship to unionists through the person of Queen Elizabeth for which many unionists have a deep affinity''.
"It is an offer I hope many will accept in the same spirit it was offered,'' he said.
The handshake at Stormont was not the only time the Queen and Mr McGuinness exchanged pleasantries. They met on a number of occasions, including at the unveiling of a portrait painted by Irish artist Colin Davidson for Cooperation Ireland. (Pictured below)
