Leo Varadkar (Dublin West, Fine Gael) | Oireachtas source

This always happens because Sinn Féin does not want to hear the facts. We all know what happened in Northern Ireland where the party's representatives voted to transfer the powers relating to welfare back to London in order to avoid making decisions. They then tried to claim they never had those powers. In fact, they did have those powers but they voted to transfer them back to London for a period of time so that the British Government could make decisions for them. That is what Sinn Féin means when it talks about republicanism and sovereignty. It is about making popular decisions when it suits and, when it does not, transferring the decisions to others.
