English: 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?
Welsh: Unwaith eto, rwy'n dilyn sbin cefnogwyr Brexit, fel y clywsom yn ystod y ddadl ar y refferendwm, ond dyna ni. A gaf fi ddiolch i Blaid Cymru am gyflwyno'r ddadl hon y prynhawn yma? Oherwydd mae'n rhoi cyfle inni dynnu sylw at y risgiau sy'n ein hwynebu wrth inni adael yr UE heb unrhyw fath o gytundeb o ran sut rydym yn masnachu gyda'n partneriaid presennol yn y dyfodol. Nawr, gwn fod Plaid Cymru wedi ymladd dros aros yn yr UE yn y refferendwm, fel y gwnes innau. Ymladdasom yn galed, ond yn anffodus, hoffwn pe bai'r bleidlais wedi bod o'n plaid. Efallai byddai amlygu beth fyddai canlyniadau a chymhlethdodau gadael y farchnad sengl fel y mae'r cyfryngau yn ei wneud erbyn hyn wedi ein helpu ar y pryd. Fodd bynnag, ni ddigwyddodd, a'r gwahaniaeth yn awr, efallai, yw fy mod i'n dymuno parchu'r rhan fwyaf o fy etholwyr a'u safbwyntiau, ac efallai y rhan fwyaf o'u rhai hwythau - er y gwn fod y Llywydd mewn sefyllfa wahanol, am fod ei mwyafrif hi mewn cyfeiriad ychydig yn wahanol - gan ddiogelu ein heconomi a'r hawliau sylfaenol a gawsom drwy fod yn yr UE. Mae'n siomedig felly, mewn gwirionedd, fod ffocws y ddadl heddiw gan Blaid Cymru wedi'i seilio'n fwy ar semanteg 'yr undeb tollau' ac 'undeb tollau', fel rydym newydd glywed gan y Ceidwadwyr hefyd, yn hytrach na'r angen i sicrhau'r canlyniadau a fydd yn diogelu ein heconomi a lles ein dinasyddion. Gadewch inni fynd yn ôl at y cwestiwn pwysig ynglŷn â beth fyddai gadael yr undeb tollau yn ei olygu i ni mewn gwirionedd. Credaf fod hynny'n bwysig. Ar yr olwg gyntaf: gwiriadau tollau ar ffiniau'r UE, gan gynnwys y ffin rhwng Gogledd Iwerddon a Gweriniaeth Iwerddon. Gwn fod hynny'n rhywbeth y mae Theresa May wedi dweud nad yw hi ei eisiau, ac mae hi'n dal ati i ddweud ei bod yn gweithio i sicrhau nad yw'n digwydd, ond rydym hefyd wedi tynnu sylw at gwestiwn gwiriadau tollau yn ein porthladdoedd. Gwn fod yr Aelod dros Ynys Môn wedi cyfeirio at y pwynt hwn yn fynych yn ei gyfraniadau yn y Cynulliad, a gofynnaf i'r Aelodau ailddarllen adroddiad y pwyllgor materion allanol ar yr effaith ar borthladdoedd Cymru a busnesau yng Nghymru o ganlyniad. Mae'n rhywbeth y gallai fod angen i chi atgoffa eich hun yn ei gylch o bosibl. Clywsom sylwadau llefarydd y Ceidwadwyr y bydd technoleg yn datrys y problemau: gwiriadau drwy dechnoleg ddeallus, meddalwedd adnabod rhifau cerbydau, gan ddefnyddio masnachwyr dibynadwy awdurdodedig, a hyd yn oed cysyniad Boris Johnson fod gwiriadau tollau yn debyg i daliadau atal tagfeydd - pwy a ŵyr?
