European Union Bill

My Lords, fascinating though the discussion about chocolate and whisky has been, I should like to return to the substance of the amendment and begin by mentioning the concerns over the figures relating to QMV. We perhaps overegg matters relating to the percentage change to the UK’s influence over further accessions. The UK currently has 12.33 per cent of the EU population. If Turkey, Croatia, Iceland and the western Balkans all joined the EU, the UK’s population would represent 10.33 per cent. Would a shift from 12.3 per cent to 10.3 per cent really warrant a referendum? Accession does not mean that we are losing our veto. This provision is not needed in the Bill, because accession treaties do not transfer power or competence from the UK to Brussels; rather, that is relevant for the country that is joining. When a country wants to join, an Act of Parliament is required, as is required for all treaty changes. As an aside, I should say that accession of a country does not lead to the loss of the British veto in any area. We covered that at length earlier in Committee. If the issue of a country joining were to be extremely sensitive, then of course a referendum could be called as part of the Act being passed by this Parliament. The referendum is there as a back-up on a particular issue, should our Parliament call upon it, but such a provision is not needed in the Bill.
