@rtenews: The Sinn Féin Leader, Mary Lou McDonald, has described as historic, the signing of an agreement by the heads of devolved governments in Northern Ireland, Scotland and Wales which said no Westminster government had the right to "block democracy". Mary Lou McDonald was speaking at a meeting in Cardiff where Michelle O'Neill, John Swinney and Rhun ap Iorwerth outlined their push for referendums on independence. The group called on the British government to "prepare for, plan and facilitate constitutional change". 📲#ireland #news #sinnfein
