Speaking of the future, I announced on 5 October that Taith's pathway 2 is now open for applications.

Yn sôn am y dyfodol, gwnes i ddatgan ar 5 Hydref fod llwybr 2 Taith ar agor nawr i ymgeiswyr.

Thank you for the question. The Building (Amendment) (Wales) Regulations 2019 were made by the then Minister for Housing and Regeneration as an immediate response to the Hackitt report, following the independent inquiry into the Grenfell tragedy. The Welsh Government is using both legislative and non-legislative levers to make further improvements in building safety.

Diolch am eich cwestiwn. Rhoddwyd Rheoliadau Adeiladu (Diwygio) (Cymru) 2019 ar waith gan y Gweinidog Tai ac Adfywio ar y pryd fel ymateb uniongyrchol i adroddiad Hackitt, yn dilyn yr ymchwiliad annibynnol i drasiedi Grenfell. Mae Llywodraeth Cymru'n defnyddio ysgogiadau deddfwriaethol ac anneddfwriaethol i wneud gwelliannau pellach i ddiogelwch adeiladau.

There is an alternative for Tata as well. They could strengthen the deal. Ratan Tata came out of retirement because he was appalled by the kind of slash and burn short-termism that Cyrus Mistry had injected into the company. His new leadership represents a return to Tata's traditional values of fairness and long-termism, and I think now we should appeal to the interim, emeritus chair of Tata Steel at a global level. Let's have that fairness. Let's have that long-term approach. The steelworkers of Wales deserve nothing less.

Mae yna ddewis arall i Tata hefyd. Gallent gryfhau'r cynnig. Daeth Ratan Tata allan o ymddeoliad oherwydd ei fod yn arswydo at y math o ymagwedd slaes a llosgi fyrdymor yr oedd Cyrus Mistry wedi'i chwistrellu i mewn i'r cwmni. Mae ei arweinyddiaeth newydd yn arwydd o ddychwelyd at werthoedd traddodiadol Tata o degwch ac ymagwedd hirdymor, ac rwy'n meddwl y dylem apelio yn awr ar gadeirydd emeritws dros dro Tata Steel ar lefel fyd-eang. Gadewch i ni gael y tegwch hwnnw. Gadewch i ni gael yr ymagwedd hirdymor honno. Nid yw gweithwyr dur Cymru yn haeddu dim llai.

Thank you very much. I've been enjoying the conversation this morning, and I'm very grateful to Heledd for her presentation too. And I agree with the analysis that you've presented to us in this document. I think it's important and very influential. You've mentioned how you try and implement various policies and the different options available to you. Do you think that there's enough leadership shown by Welsh Government?

Diolch yn fawr. Dwi wedi bod yn mwynhau'r sgwrs y bore yma, a dwi'n ddiolchgar i Heledd am y cyflwyniad hefyd. A dwi'n cytuno gyda'r dadansoddiad dŷch chi wedi cyflwyno i ni yn y ddogfen yma. Dwi'n credu ei fod e'n un pwysig, ac yn ddylanwadol iawn, y ffordd dwi wedi darllen drwyddo fe. Mi rydych chi wedi sôn amboutu sut rydych chi'n trio gweithredu polisïau gwahanol ac opsiynau gwahanol. Ydych chi'n meddwl bod yna ddigon o arweinyddiaeth gan Lywodraeth Cymru?

I just want to ask a rather tangential but relevant question. We have variable speed limits already on motorways depending on the type of vehicle - different speed limits for vans and lorries to cars. Could electric vehicles travel at faster speeds considering that they don't pollute the atmosphere?

Hoffwn ofyn cwestiwn braidd yn ymylol ond perthnasol. Mae gennym ni derfynau cyflymder amrywiol eisoes ar draffyrdd yn dibynnu ar y math o gerbyd - gwahanol derfynau cyflymder ar gyfer faniau, lorïau a cheir. A allai cerbydau trydan deithio ar gyflymder uwch gan ystyried nad ydynt yn llygru'r amgylchedd?
