It is a pleasure to speak today to the Plaid Cymru amendments and in favour of those amendments, of course, and I do so on behalf of the Arfon constituency, one of the constituencies that was most robust in its support for remaining within the European Union, with over 60 per cent having voted to remain. And, according to a recent opinion poll, 71 per cent of the people of Arfon would now vote to remain, should there be a second vote—and the only way out of this mess is a second vote, a people's vote. There is no purpose in having a general election. Jeremy Corbyn would not campaign to remain in the single market. Therefore, you would have more confusion, more uncertainty, if he were to win a general election. So, I urge you on the Labour benches who know that in your own hearts—do support amendment 3 in the name of Plaid Cymru. That's why we have tabled it here today.

The people of Arfon have come to the conclusion that remaining in the single market and customs union is the best possible solution for everyone living there. Therefore, on their behalf this afternoon, I state that I am rejecting the Theresa May withdrawal agreement. The economic argument is clear. The Arfon constituency is part of west Wales and the Valleys, and gross domestic product is low, and as a result it receives funding from the European Union—similar to southern Spain, Portugal and the former communist states within Europe. Arfon also receives INTERREG funding to promote connections with the Republic of Ireland, and there is some concern locally about the lack of detail, the shocking lack of detail, as to what will replace those funding sources for the future.

Bangor University and Ysbyty Gwynedd are in the Arfon constituency, and both institutions have a high number of staff from other EU nations, as well as students at Bangor University, of course. One of the largest private sector employers in Arfon is a German company working in medical technologies. Arfon is a tv production centre that works with other broadcasters within the European Union, and Arfon is one of the areas where the Welsh language is strongest, with 85 per cent of young people having benefited from bilingual education provision. Speaking two, three, four languages is normal within the European Union at an official, social and cultural level, which gives us confidence that the Welsh language will survive within that European context. Outwith that union, the future is less hopeful. That partially explains the substantial support in Arfon for remaining within the EU. Sustaining people's rights and equality legislation is crucial to that too.

Turning now to the second part of my comments this afternoon, it's a privilege for me to work with the MP for Arfon, Hywel Williams, who is part of an active and very effective Plaid Cymru team in London. Wales is fortunate in the four who are battling for our nation in the corridors of power in London. Hywel has taken a full part in the discussion on Brexit, has introduced numerous amendments to the EU withdrawal Bill, and has contributed eagerly as a member of the EU withdrawal select committee. He and Plaid Cymru have been entirely consistent in opposing withdrawal before the referendum, and we are in favour of remaining within the single market and the customs union. That is why Hywel, along with others, took part in a case in the European Court recently.

Today, there was confirmation of what Plaid Cymru has been arguing. The senior adviser of the European Court of Justice has stated today that he is of the view that the UK could abolish article 50 and remain within the European Union without the need for the consent of the other nations of the union. This is contrary to what Mrs May has been saying. This, in my view, is a game changer, and enables the Government—not the Westminster Parliament—to scrap the process if they want to avoid a 'no deal' Brexit, or if a people's vote demonstrates that public opinion has shifted since 2016. We're expecting confirmation of this decision in the European Court of Justice before Christmas and, believe you me, this could be of huge significance for my constituents in Arfon, for the people of Wales, and for the future of our nation. So, today, I do urge you to join us on these benches in sending an unambiguous message from our national Senedd, and I therefore ask you to support the Plaid Cymru amendments.
