Diolch, Lywydd. Hoffwn ddechrau, os caf, drwy gywiro rhai sylwadau a wnaethpwyd ddoe gan arweinydd y Ceidwadwyr, a honnodd fod amseroedd aros ambiwlansys yng Nghymru yn gwella. Mewn gwirionedd, mae'r amseroedd ymateb canolrifol i alwadau coch yn waeth y gaeaf hwn na'r gaeaf diwethaf - mae llai yn cyrraedd o fewn y targed wyth munud. O ran galwadau oren, mae bron i hanner yn cymryd dros 30 munud i gyrraedd bellach - bron ddwywaith mor wael â'r gaeaf diwethaf. Ac mae ein parafeddygon rhagorol yn dweud wrthyf eu bod yn digalonni o ddifrif. Pam fod ambiwlansys yn cymryd mwy o amser i gyrraedd bellach, mewn argyfyngau ac mewn achosion brys a galwadau oren, nag yn y blynyddoedd diwethaf?

Diolch, Llywydd. I'd like to begin, if I could, by correcting some comments made yesterday by the leader of the Conservatives, who claimed the ambulance waiting times in Wales were improving. In fact, the median response times to red calls are worse this winter than last winter - fewer are arriving within the target eight minutes. When it comes to amber calls, almost half are now taking longer than 30 minutes to arrive - almost twice as bad as last winter. And our excellent paramedics tell me that they're really, really losing heart. Why are ambulances taking longer to arrive now, in emergency and in urgent, amber call cases, than in previous years?

Atgoffaf y Prif Weinidog mai ef sy'n gyfrifol am bolisi iechyd yma yng Nghymru. Ac nid yw hyn yn ymwneud ag ysbytai yn unig, y polisi penodol hwn, ond mae hefyd yn ymwneud â'n hysgolion. Dangosodd papur a gyhoeddwyd gan Sefydliad Nuffield ac Athrofa Addysg UCL bod un o bob pedwar o athrawon yn gweithio mwy na 60 awr yr wythnos yn y DU. Rydym ni'n gwybod bod eich Llywodraeth chi wedi ei gwneud yn eglur nad oes ganddi unrhyw gynlluniau i gau ysgolion am ddiwrnod ychwanegol yr wythnos, sydd i bob pwrpas yn golygu y byddai'n rhaid i benaethiaid, o dan Lywodraeth Lafur y DU yn y dyfodol, gyflogi staff ychwanegol a newid eu rotas yn sylweddol er mwyn sicrhau wythnos waith lai. Prif Weinidog, pa goeden arian hudol sydd gan Lywodraeth Cymru i gyflawni'r amcan hwn mewn gwirionedd? A sut gwnewch chi ddenu athrawon i Gymru, o gofio bod eich Llywodraeth eich hun wedi methu ei thargedau ei hun ar gyfer athrawon uwchradd dan hyfforddiant newydd gan 40 y cant eisoes eleni?

I remind the First Minister that he is responsible for health policy here in Wales. And this is not just about hospitals, this particular policy, but it's also about our schools too. A paper published by the Nuffield Foundation and UCL Institute of Education showed that a quarter of teachers work more than 60 hours per week in the UK. We know that your Government has made it clear that it has no plans to close schools for an extra day a week, which effectively means that headteachers, under a future UK Labour Government, would have to hire additional staff and drastically change their rotas in order to achieve a reduced working week. First Minister, what magical money tree does the Welsh Government have to actually meet this objective? And how will you attract teachers to Wales, given that your own Government has missed its own targets for new secondary trainee teachers by 40 per cent already this year?

Wrth gwrs, fe allwch chi ofyn beth liciwch chi, ond mae'n 11:03 ac fe fyddwch chi'n cwyno yn y funud nad ydw i'n aros mwy nag awr.

Of course, you can ask what you like, but it's 11:03 and you'll be complaining in a minute that I can't stay for more than an hour.
