European Union Bill

The principle on which the Government have consistently sought to act in preparing and introducing this legislation has been that a change to the treaties that transferred new competencies or powers from the United Kingdom to the institutions of the European Union would require the agreement of the British people in a referendum. That is the principle, so for us the test for the sort of hypothetical treaty change that my hon. Friend is describing would be whether it transferred competencies or powers from this country to the EU. I do not want to stray too far from the subject of the Lords amendments we are discussing, but the hypothesis that he describes could just as well be a question of a quite separate intergovernmental treaty between members of the eurozone, for example, as an amendment to the treaty of Lisbon, which would require the assent of the United Kingdom.
