Mater i gadeirydd yr ymchwiliad yw penodi arbenigedd cyfreithiol. Mae Llywodraeth Cymru wedi ymrwymo i gefnogi'r ymchwiliad, a bu'n rhagweithiol wrth fynd ati i wneud yr ymchwiliad yn ymwybodol o drefniadau cyfansoddiadol a chyfreithiol Cymru fel bod modd asesu lefelau o arbenigedd.

Determining legal expertise is a matter for the chair to the inquiry. The Welsh Government is committed to supporting the inquiry, and has been proactive in making the inquiry aware of Wales's constitutional and legal arrangements so that levels of expertise can be assessed.

Pam oedd hynny, ys gwn i.

I wonder why that was.

Diolch am eich ateb, Weinidog Cyllid. Yn amlwg, ym mis Ebrill, fe wnaeth Llywodraeth Cymru ddatganiad ar yr argyfwng newid hinsawdd. Nododd fy nghyd-Aelod Nick Ramsay fod eich sylwadau ddoe yn dweud bod hon yn gyllideb werdd. Mae Cyfoeth Naturiol Cymru, eich rheoleiddiwr eich hun ar gyfer llawer o'r pethau ym maes yr amgylchedd, wedi cael cyllideb wastad, sydd i bob pwrpas yn doriad mewn termau real. A allwch gadarnhau p'un a gawsoch unrhyw sylwadau gan Weinidog yr amgylchedd i geisio sicrhau cynnydd mewn termau real yng nghyllideb CNC, neu a ydych heb dderbyn unrhyw sylwadau? Ac os na fydd cynnydd yn eu cyllideb, sut y disgwyliwch i Cyfoeth Naturiol Cymru gyflawni'r swyddogaethau rydych wedi'u rhoi iddynt?

Thank you, finance Minister, for that answer. Obviously, in April there was the declaration by the Welsh Government of the climate change emergency. My colleague Nick Ramsay highlighted that your comments yesterday were saying that this was a green budget. Natural Resources Wales, which is your own regulator for many of the things in the environmental field, has had a flatline budget, which in effect is a real-terms cut. Can you confirm whether you did receive any representations from the environment Minister to try and secure a real-terms increase in NRW's budget, or haven't you received any representations? And if there is to be no increase in its budget, how do you expect Natural Resources Wales to undertake the functions you've placed on it?

Dywed y Sefydliad Cenedlaethol er Ymchwil i Addysg fod galw nad yw'n cael ei ddiwallu gan athrawon uwchradd neu athrawon ysgolion uwchradd sy'n awyddus i gwtogi neu newid eu horiau. Maent yn amcangyfrif yr hoffai un o bob chwe athro gwtogi eu horiau ac maent yn annog arweinwyr ysgolion uwchradd i wneud mwy i ddarparu ar gyfer athrawon sy'n awyddus i weithio'n rhan-amser neu'n hyblyg. Weinidog, a gaf fi ofyn pa sylwadau rydych wedi'u cael ar y mater hwn a pha ganllawiau a roesoch i ysgolion mewn perthynas â gweithio'n rhan-amser ac yn hyblyg, gan fod diffyg y math hwnnw o weithio yn ffactor pwysig ym mhenderfyniad rhai athrawon i adael y proffesiwn yng Nghymru?

The National Foundation for Educational Research says that there is an unmet demand from secondary teachers or secondary school teachers wanting to reduce or alter their hours. They estimate that one in six teachers would like to reduce their hours and urge secondary school leaders to do more to accommodate teachers who want to work part-time or flexibly. Minister, can I ask what representations you have received on this matter and what guidance you have issued to schools with regard to part-time and flexible working, the lack of which is an important factor in some teachers leaving the profession in Wales?
