On the road to unity - is it time for a referendum to bring north and south together again?

Sinn Féin's Vice-President says there should be a referendum on Irish unity within the next five years. Michelle O'Neill was speaking at an Easter parade in Milltown cemetery in west Belfast on Sunday. Sinn Fein's Vice-President also said she was confident of the benefits a united Ireland would bring and that unionists would be treated as equals in it. Do you want a referendum? A chance to vote for what you believe in? Whether that be the United Kingdom - out of Europe - or a United Ireland very much in the European Union? Vinny got the views of commentator Chris Donnelly and former DUP MLA Nelson McCausland.
