Well, we delivered on the results of the referenda in 1997 and 2011. And I'm perfectly happy to see the Labour Party commit itself to going back into the EU once we've left; what it did not have the moral right to do was to attempt to frustrate the result of the referendum before it had actually been delivered. It's a perfectly honourable role for other parties to say, 'We are better off inside the EU', and to campaign. I think it would be a brave step for them to take, and I hope, indeed, that they take it up, because that will, I think, help to consign them to the irrelevance which they have arrived at for the foreseeable future.

But this debate is not about workers' rights or any of the other ingredients of the referendum campaign. I don't want to see any rolling back on the rights of workers any more than any other Member does in this house. This is all about legislative competence. This is what democracy is all about. Nations, for good or ill, take decisions. Through elections, they elect Governments to introduce laws and to change laws. And if we're not going to have a sovereign Parliament in that respect, then, effectively, we haven't left the EU at all in those particulars.

So this, ultimately, is all about what kind of a country are we and what kind of a nation are we. What kind of electoral system to deliver on the democratic will of the people have we got? It's amazing that we have a nationalist party, so-called, in this place that doesn't actually believe in national independence as expressed through representative institutions; they'd much rather be governed from a technocratic elite that we don't elect and can't even name in most cases, based in Brussels.

This was a vote by the British people and the Welsh people for independence and the supremacy of their parliamentary institutions, including this one here in Cardiff. The fulfilment of what the people voted for three and a half years ago is an historic moment for this country, and I'm afraid the Labour Party, and Plaid Cymru in particular, have failed the people who have elected them.
