Historic day as the leader of unionism to attend funeral of former IRA commander - @malodoherty and @JimAllister discuss

A historic moment in the history of Northern Ireland. The once unthinkable will happen in L'derry later today, as the leader of unionism attends the funeral of a former IRA commander. Arlene Foster - the DUP leader - will attend the funeral of her former partner in government Martin McGuinness. The man who removed her from office in January in his last political act. But also the man who was a commander in an organisation who tried to murder her father. The man who gave a graveside oration at the funeral of the IRA man who, she believes, tried to murder her father. An organisation who planted a bomb on her school bus. He was also the man who her party has shared power with for a decade, with often troubled relationships. But has this gesture by Arlene Foster come too late? Or is this a game changer in relations between Northern Ireland's biggest political parties? Commentator Malachi O'Doherty and TUV MLA Jim Allister discuss.
