We may make strange bedfellows, but Normal Mouth and View from the Glen agree with my view that a referendum on the next step for the National Assembly is unnecessary.
I can't see the constitutional value of a referendum based on the Government of Wales Act 2006, because the result of the referendum won't change the powers that the Assembly has. A yes vote will just simplify the way that those powers are accessed. A no vote will keep hurdles - it won't change powers.
As a general point, Gordon Brown has said that he wants to review the Union's constitution. In doing so he would be wise to consider passing a Referendum Act that makes it clear when and why referenda are called.
An ad-hoc use of referenda for political expediency isn't democratic. If referenda are to be used at all in the political process, then consistent constitutional law, rather than a government's fancy should trigger them.
