Diolch, Lywydd. Mae'r Prif Weinidog yn ceisio cystadlu ag arweinydd Plaid Cymru fel rhyw fath o Jeremeia Cymru heddiw o ran dyfodol Cymru y tu allan i'r UE. Mae'n ddrwg gennyf ei glywed yn dweud ei fod yn erbyn trethi is ar fusnes, gan fod gweriniaeth Iwerddon wedi defnyddio cyfradd is o dreth gorfforaeth yn llwyddiannus iawn i ddenu nifer fawr o gwmnïau i mewn i Ddulyn, yn enwedig yn y sector gwasanaethau ariannol. Felly, mae'n ymddangos i mi yn gwbl wrthgynhyrchiol i fuddiannau Cymru i ddiystyru hyn ar gyfer y dyfodol. Yr wythnos diwethaf, dywedodd y Prif Weinidog, o ran y farchnad sengl: Nid wyf yn credu y gallwch chi gael mynediad at y farchnad sengl a dweud ar yr un pryd eich bod eisiau cael rheolaeth lawn ar fewnfudo. Wel, dyna'n union sydd gennym ni gyda chytundeb masnach De Corea; pam nad yw hynny'n mynd i fod yn bosibl i ni ym Mhrydain?

Diolch, Lywydd. The First Minister is trying to compete with the leader of Plaid Cymru as a sort of Jeremiah of Wales today in relation to Wales's future outside the EU. I'm sorry to hear him say that he is against lower taxes on business, because the Irish republic has very successfully used a lower rate of corporation tax to attract a huge number of firms into Dublin, particularly in the financial services sector. So, it seems to me wholly counter-productive to Wales's interests to rule this out for the future. Last week, the First Minister said, in relation to the single market: 'I don't believe you can have access to the single market and, at the same time, say that you want full control over immigration.' Well, that's exactly what we do have with the South Korea trade agreement; why isn't that going to be possible for us in Britain?

Wel, fel y dywedwch chi, cyflwynodd Ysgrifennydd y Cabinet dros yr Economi a Thrafnidiaeth ddatganiad ysgrifenedig ar 21 Chwefror. Amlinellodd ei gynlluniau ar gyfer dyfodol teithio ar fysiau am bris gostyngol i bobl ifanc. Rydym ni wedi cytuno ag awdurdodau lleol a'r diwydiant bysiau y bydd y trefniadau teithio gostyngol presennol yn parhau, fel y dywedais wrth ateb eich cwestiwn cyntaf. Rydym ni wedi derbyn cynnig y Cydffederasiwn Cludiant Teithwyr i wneud cynigion ar gyfer ymgyrch farchnata newydd, gan ein bod ni'n gwybod bod angen i ni gynyddu nifer y bobl sy'n manteisio ar basys ac yn eu defnyddio, ond rydym ni'n bwriadu lansio cerdyn teithio newydd o 2018. Byddwn yn ymgynghori dros yr haf.

Well, as you say, the Cabinet Secretary for Economy and Transport did issue a written statement on 21 February. He outlined his plans for the future of young persons' discounted bus travel. We've agreed with local authorities and the bus industry that the existing discounted travel arrangements will continue, as I said in answer to your first question. We've accepted the Confederation of Passenger Transport's offer to come forward with proposals for a new marketing campaign, because we know we needed to increase the uptake and use of passes, but we intend to launch a new travel pass from 2018. We'll be consulting over the summer.

Gyda hynny, symudwn at eitem 1, sef cwestiynau i Weinidog yr Economi, Trafnidiaeth a Gogledd Cymru, a daw'r cwestiwn cyntaf gan Angela Burns.

With that, we'll move to item 1, which is questions to the Minister for Economy, Transport and North Wales, and the first question is from Angela Burns.

Tybed a oes modd iddo hefyd ymdrin â'i welliant ei hun, sy'n dweud y bydd y DU yn aros yn y farchnad sengl, i bob pwrpas. Onid i Ogledd Iwerddon y byddai hynny, mewn gwirionedd, yn digwydd? Ac yna mae'n dweud bod Llywodraeth y DU wedi amharu ar Brexit. Mewn gwirionedd, hyd yn hyn, rydym yn mynd i adael ar 29 Mawrth, ac rwy'n gobeithio ac yn credu y bydd hynny'n dal i ddigwydd, ac onid yw e'n cytuno â hynny?

I wonder if he might also just address his own amendment, which says that the UK will effectively stay in the single market. Isn't it actually Northern Ireland that that would happen to? And he then says that the UK Government has frustrated Brexit. Actually, to date, we're to leave on 29 March, and I hope and believe that will still happen, and doesn't he agree with that?

Diolch i'r Aelod am y cwestiwn. Rwy'n cyfeirio'r Aelod at yr ateb a roddais wrth ymateb i'r cynnig ar 18 Ebrill. Mae'n amlwg bod gwahaniaeth barn dilys ynglŷn â'r dehongliad o adran 37, ac rŷm ni'n cynnal deialog adeiladol gyda'r Llywydd i ddatrys hyn.

May I thank the Member for the question? I refer the Member to the answer I gave in responding to the motion on 18 April. It's clear that there is a legitimate difference of opinion about the interpretation of section 37, and we are engaging in constructive dialogue with the Presiding Officer to resolve this.
