The constitutional treaty is now defunct. The Inter-Governmental Conference Mandate agreed by the June European Council states that
“The constitutional concept has been abandoned.”
While all member states have moved away from the constitution, the UK has a specific treaty deal which means we have moved further than anyone else from the constitution.
The UK has only ever held one national referendum, which was in 1975. We will seek parliamentary ratification of this Reform Treaty. In doing so we shall adopt a similar approach to that adopted by the Governments of Tony Blair, Sir John Major and Baroness Thatcher.
