I follow, once again, the spin of the Brexiteers, as we heard during the debate on the referendum, but there we go. Can I thank Plaid Cymru, actually, for bringing this debate forward this afternoon? Because it is providing us an opportunity to highlight the risks that face us as we leave the EU without any form of agreement on how we trade with our existing partners in the future.

Now, I know Plaid Cymru fought to remain in the EU in the referendum, as did I. We fought hard, but unfortunately, I wish the vote had been in our favour. Perhaps the realisation of the consequences and complexities of leaving the single market that are now in the media being highlighted would've helped us at that time. However, it didn't, and the difference, perhaps, that we have now is that I wish to respect the majority of my constituents and their views, and perhaps the majority of theirs—although I know the Llywydd is in a different position, because her majority was slightly in a different direction—whilst we protect our economy and the fundamental rights that we have had by being in the EU. It's therefore disappointing, actually, that the focus of today's debate by Plaid Cymru is more based upon the semantics of 'the customs union' and 'a customs union', as we've just heard from the Conservatives as well, rather than the need to secure the outcomes that will protect our economy and the welfare of our citizens.

Let's go back to the important question of what would leaving the customs union actually mean to us. I think that is important. On the face of it: customs checks at EU borders, including the border between Northern Ireland and the Republic of Ireland. I know that it's something that Theresa May has said that she doesn't want, and keeps saying that she's working to ensure that it doesn't happen, but we've also highlighted the question of custom checks at our ports. I know the Member for Ynys Môn has often referred to this point in his contributions in the Assembly, and I'd ask Members to re-read the external affairs committee's report on the impact on Welsh ports and on Welsh businesses as a consequence. It is something that you perhaps need to refresh your memories on.

We heard the comments from the Conservatives' spokesperson that technology will solve the problems: checks through smart technology, number plate recognition software, using authorised trusted traders, and maybe even Boris Johnson's concept of congestion charges being equated to customs checks—who knows?
