English: As David Rees has already said, the promise during the referendum was that we would be no worse off if we left the European Union, and it's up to the UK Parliament to ensure that whatever deal is agreed by Mrs May, and she brings back to the UK Parliament, meets those criteria. Otherwise, they ought to know what to do with it. What our job is is to articulate the needs of Wales and how Wales will not have its devolved powers rowed back on as a result of leaving the European Union. We have already rehearsed the problems around the LDEU and the referral to the Supreme Court, so this is a discussion that's going to go on and on. But I think that we need to be wise to the rhetoric that has been surrounding this versus the reality. When members of the committee visited Toyota in Deeside in February, it was made very clear to us that it would be a disaster if the just-in-time goods that they import into Felixstowe were going to be delayed as a result of us no longer having a single market arrangement, and that if there were additional customs checks in Felixstowe, it would obviously put a major question mark over whether or not Toyota would continue in the UK. It was therefore a very pleasant surprise to see that Toyota has actually agreed to build the latest engine at Deeside, which was announced after our visit. I think one of the issues for me is not just the time that all the big brains in Welsh Government are having to deploy on this subject when we could be dealing with other more pressing matters like eliminating poverty or sorting out homelessness, but that the cost of leaving the EU could be huge. Mrs May, in her speech at the Mansion House, for example, identified a number of EU agencies that she wanted the UK to continue to be involved in as an associate member. She mentioned the European Medicines Agency, the European Chemicals Agency and the European Aviation Safety Agency as ones that she had in mind. Our discussions with stakeholders made it clear that those three are very important to the continued functioning of Welsh organisations. Cardiff Airport warned that if they were not part of the European Aviation Safety Agency, it would have a considerable impact on their ability to compete with other European airports and would certainly put new costs and new delays on their operations. The NHS Confederation, the Royal College of Nursing and the British Medical Association were all clear that we need to be part of the European Centre for Disease Prevention and Control as well as the European Medicines Agency. Leanne Wood has already referred to the fact that if we're not part of the European Medicines Agency, we will be at the back of the queue in terms of getting new medicines, because we will no longer be a large-enough economy to merit new medicines being given priority to our country, so that is obviously a very serious matter. When we were in Brussels at the end of last month, one of the people we saw was Mr Stanislav Todorov, the permanent representative of Bulgaria, who is an extremely important figure at the moment, because Bulgaria holds the presidency of the European Union, so what he had to say is very important. He was perfectly clear with us - he was refreshingly clear and candid, in fact - about the expectations being raised by Mrs May and others. He said, 'Look, these agencies are all about strengthening the single market, and if the UK is not part of the single market, ergo they are not going to be members of these agencies.' Obviously, we can negotiate some sort of observer status, but it doesn't look very promising if the hard line adopted by Bulgaria is played out across the rest of the EU. Therefore, we have to then ask ourselves what the cost is going to be of setting up similar regulatory bodies in the UK, which is money that we, therefore, don't have to spend on other things like insulating all our homes. So, I think there's a real tendency to want to have our cake and eat it on this one, but I hope that this report is a useful summary of some of the issues that we need to continue to pursue to protect Wales's interests.
Welsh: Fel y dywedodd David Rees eisoes, yr addewid yn ystod y refferendwm oedd na fyddem yn waeth ein byd pe baem yn gadael yr Undeb Ewropeaidd, a mater i Senedd y DU yw sicrhau bod pa fargen bynnag a gytunir gan Mrs May, ac y daw â hi'n ôl i Senedd y DU, yn bodloni'r meini prawf hynny. Fel arall, dylent wybod beth i'w wneud â'r fargen honno. Ein gwaith ni yw mynegi anghenion Cymru a sut nad yw Cymru'n mynd i oddef colli ei phwerau datganoledig o ganlyniad i adael yr Undeb Ewropeaidd. Rydym eisoes wedi trafod y problemau sy'n ymwneud â'r gyfraith sy'n deillio o'r Undeb Ewropeaidd a'r cyfeiriad i'r Goruchaf Lys, felly dyma drafodaeth sy'n mynd i barhau. Ond credaf fod angen inni fod yn ddoeth yn wyneb y rhethreg sydd ynghlwm wrth hyn yn erbyn y realiti. Pan ymwelodd aelodau'r pwyllgor â Toyota yng Nglannau Dyfrdwy ym mis Chwefror, dywedwyd yn glir iawn wrthym y byddai'n drychineb pe bai'r nwyddau mewn union bryd y maent yn eu mewnforio i Felixstowe yn mynd i gael eu dal yn ôl o ganlyniad i'r ffaith na fyddai gennym drefniant marchnad sengl bellach, a phe bai gwiriadau tollau ychwanegol yn Felixstowe, byddai'n amlwg yn codi cwestiwn ynglŷn ag a fyddai Toyota yn parhau yn y DU ai peidio. Felly roedd hi'n braf iawn gweld bod Toyota wedi cytuno i adeiladu'r injan ddiweddaraf ar Lannau Dyfrdwy, cyhoeddiad a wnaed ar ôl ein hymweliad. Credaf mai un o'r problemau i mi yw nid yn unig yr amser y mae'r holl ymenyddiau mawr yn Llywodraeth Cymru yn gorfod ei dreulio ar y pwnc hwn pan allem fod yn ymdrin â materion eraill mwy taer fel dileu tlodi neu ddatrys digartrefedd, ond hefyd y gallai'r gost o adael yr UE fod yn enfawr. Yn ei haraith Mansion House, er enghraifft, nododd Mrs May nifer o asiantaethau'r UE yr oedd am i'r DU barhau i gymryd rhan ynddynt fel aelod cyswllt. Soniodd am yr Asiantaeth Feddyginiaethau Ewropeaidd, yr Asiantaeth Gemegion Ewropeaidd ac Asiantaeth Diogelwch Hedfan Ewrop fel rhai a oedd ganddi mewn golwg. Gwnaeth ein trafodaethau â rhanddeiliaid hi'n glir fod y tair asiantaeth honno'n bwysig iawn i weithrediad parhaus sefydliadau Cymreig. Rhybuddiodd maes awyr Caerdydd os na fyddent yn rhan o Asiantaeth Diogelwch Hedfan Ewrop, y byddai'n effeithio'n sylweddol ar eu gallu i gystadlu â meysydd awyr Ewropeaidd eraill a byddai'n sicr yn creu costau newydd ac oedi newydd i'w gweithrediadau. Roedd Cydffederasiwn y GIG, y Coleg Nyrsio Brenhinol a Chymdeithas Feddygol Prydain oll yn glir fod angen inni fod yn rhan o'r Ganolfan Ewropeaidd ar gyfer Atal a Rheoli Clefydau yn ogystal â'r Asiantaeth Feddyginiaethau Ewropeaidd. Mae Leanne Wood eisoes wedi cyfeirio at y ffaith y byddwn yng nghefn y ciw o ran cael meddyginiaethau newydd os nad ydym yn rhan o'r Asiantaeth Feddyginiaethau Ewropeaidd, gan na fydd gennym economi ddigon mawr mwyach i'w gwneud hi'n werth rhoi blaenoriaeth i feddyginiaethau newydd yn ein gwlad, felly mae hynny'n amlwg yn fater difrifol iawn. Un o'r bobl a welsom pan oeddem ym Mrwsel ddiwedd y mis diwethaf oedd Mr Stanislav Todorov, cynrychiolydd parhaol Bwlgaria, sy'n ffigur eithriadol o bwysig ar hyn o bryd, oherwydd mai Bwlgaria sy'n dal llywyddiaeth yr Undeb Ewropeaidd, felly mae'r hyn a oedd ganddo i'w ddweud yn bwysig iawn. Roedd yn berffaith glir gyda ni - roedd yn braf ei weld yn bod mor glir a gonest gyda ni mewn gwirionedd - ynglŷn â'r disgwyliadau sy'n cael eu codi gan Mrs May ac eraill. Dywedodd hyn: 'Edrychwch, nod yr asiantaethau hyn i gyd yw cryfhau'r farchnad sengl, ac os nad yw'r DU yn rhan o'r farchnad sengl, nid ydynt yn mynd i fod yn aelodau o'r asiantaethau hyn.' Yn amlwg, gallwn negodi rhyw fath o statws sylwedydd, ond nid yw'n edrych yn addawol iawn os yw'r ymagwedd ddiwyro a fabwysiadwyd gan Fwlgaria yn cael ei hailadrodd ar draws gweddill yr UE. Felly, mae'n rhaid inni ofyn beth fydd y gost o sefydlu cyrff rheoleiddio tebyg yn y DU, sef arian na fydd gennym, felly, i'w wario ar bethau eraill fel inswleiddio ein holl gartrefi. Felly, credaf fod yna duedd wirioneddol i fod eisiau ei chael hi bod ffordd yn hyn o beth, ond rwy'n gobeithio bod yr adroddiad hwn yn grynodeb defnyddiol o rai o'r materion y mae angen inni barhau i fynd ar eu trywydd er mwyn diogelu buddiannau Cymru.
