The discussion was chaired by Irish republican, author and former Sinn Fein Director of Publicity, Danny Morrison.

"We need to be very honest with ourselves - that [McGuinness attending a state banquet in Windsor Castle] didn't always play well with us at all levels of Irish nationalism," said Ms. McDonald.

"But here's the significant measure of Martin [McGuinness] - he knew and was convinced that this was uncomfortable, unpalatable but necessary and the right thing to do.

"Once he had that compass set in his head he would never falter, never second guess himself and for me that was his most standout quality."

"He had the capacity to make nationalist Ireland right across the island walk tall," she added.

Martin McGuinness passed away on March 21 after a short illness; he was was 66 years-old.
