Plaid Cymru and Labour both thought Arfon was going to be close. But Hywel Williams vote shot up from 36% to 44% and Alun Pugh got 30%, the same as the previous Labour candidate in 2010.
Plaid Cymru says Wales will continue to lose out after the Prime Minister told MPs that there is no reform 'on the horizon' for the Barnett Formula, which limits any change in the funding that the UK Treasury gives to the Welsh Government.
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.
A Welsh Government source has dismissed criticism by Plaid Cymru MP Hywel Williams about the First Minister's campaign for a constitutional convention. Mr Williams accused Carwyn Jones of 'bluster' for not raising it with the Deputy Prime Minister's office which is responsible for the constitution.
But the source said:
A Plaid Cymru MP says the First Minister is guilty of 'bluster' on constitutional change but not following it up with action. Carwyn Jones has repeatedly said there needs to be a constitutional convention - a formal way of looking at what powers Wales and other parts of the UK need.
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:
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.
