The National Assembly should be able to hold referenda on major issues that are legally binding, according to Plaid Cymru. It'll try to alter the Wales Bill to include the move when in its final Commons stage today.
Plaid MP Hywel Williams says 'it would make government better and more legitimate' by leaving it to 'the people of Wales' to decide which powers should be transferred to the Assembly and when.
The First Minister has led the way on calling for a Constitutional Convention. He has raised the issue many times in face-to-face discussions with both the Prime Minister and Deputy Prime Minister. As usual, Plaid Cymru are late to the table and have nothing useful to add to this debate.
But Hywel Williams asked the UK Government department responsible, the Deputy Prime Minister's office, what approaches the First Minister has made. This was the answer from Minister Greg Clark:
The Deputy Prime Minister has not received any recent representations on the topic of a constitutional convention from the Welsh Government.
On the day that Carwyn Jones intends to push the Prime Minister over the delayed decision on tax and borrowing powers for Wales, Mr Williams says that it raises questions about the First Minister's own commitment.
For all the First Minister's bluster, it seems that he's making no real progress on this.
It's becoming increasingly difficult to take him seriously when he claims to be committed to securing a better settlement for Wales. The only thing he has achieved is undermining people's confidence in his abilities.
In January last year, the First Minister called for this Convention to be set up to keep the UK together. After nearly two years of stagnation, we can now only presume that he is in favour of Scottish independence.
