Ond ydy'r partneriaethau gwahanol yn siarad gyda'i gilydd y nawr? Dŷch chi'n dweud roeddech chi'n arfer cwrdd. Ydych chi'n cwrdd nawr - Abertawe, Caerdydd -

But do the different partnerships speak to each other now? You said that you used to meet. Are you meeting now - Swansea, Cardiff and so on?

A hefyd, o ran dysgu ar draws - . Oherwydd bod y bwrdd mor fawr, os oes yna ddigwyddiad yn Wrecsam neu yn Nolgellau, rydym ni angen dysgu beth fyddwn ni'n ei wneud yn wahanol, so ein bod ni i gyd yn gwneud yr un peth. Efo'r cyfarfodydd wythnosol yma, rydym ni'n medru dysgu o'n gilydd, oherwydd mae hynny'n medru bod yn sialens mewn bwrdd iechyd mor fawr weithiau. Ond mi rydym ni angen dysgu.

And also, in terms of learning across - . Because it's such a large board, if there is an incident in Wrexham or in Dolgellau, we do need to make sure that we learn what to do differently, so that we're all doing the same thing. So, with these weekly meetings, what we're seeking to do is learn from each other, because that can be a challenge in such a large health board sometimes. But we do need to learn.

Diolch am godi eich llaw, Ddirprwy Weinidog.

Thank you for putting your hand up there, Deputy Minister.

Rwy'n cynnig gwelliant 1. Ers 2003, rwyf wedi ymgyrchu dros y sector, gan rybuddio Llywodraeth Cymru fod Cymru'n wynebu argyfwng o ran y cyflenwad o dai fforddiadwy oni bai bod camau'n cael eu cymryd ar frys. Clywsom hyn pan gawsom dystiolaeth am Ben Llŷn 15 mlynedd yn ôl. Yn lle hynny, torrodd Llywodraeth Lafur Cymru dros 70 y cant oddi ar nifer y cartrefi cymdeithasol yn ystod tri thymor cyntaf y Cynulliad, wrth i restrau aros chwyddo. Nododd adolygiad tai'r DU yn 2012 mai Llywodraeth Cymru ei hun a roddodd lai o flaenoriaeth i dai yn ei chyllidebau cyffredinol, fel mai hi, erbyn 2009-10, o bedair gwlad y DU, oedd â'r lefel gyfrannol isaf o lawer o wariant ar dai. Hyd yn oed y llynedd, 2019, y flwyddyn lle gwelwyd y nifer fwyaf o gofrestriadau cartrefi newydd yn y DU ers 2007, gostyngodd y niferoedd yng Nghymru dros 12 y cant. Felly, ni allwn gefnogi gwelliant Llywodraeth Cymru, sy'n esgus bod Llywodraeth Cymru wedi bod ag ymrwymiad hirsefydlog i ddarparu tai fforddiadwy o ansawdd da.

I move amendment 1. From 2003, I've campaigned for the sector, warning the Welsh Government that Wales faced an affordable housing supply crisis unless urgent action was taken. We heard this when we took evidence on Pen Llŷn, 15 years ago. Instead, the Labour Welsh Government cut the number of social homes by over 70 per cent during the first three Assembly terms, as waiting lists mushroomed. The 2012 UK housing review stated it was the Welsh Government itself that gave housing lower priority in its overall budgets, so that, by 2009-10, it had by far the lowest proportional level of housing expenditure of any of the four UK countries. Even last year, 2019, the highest year for UK new home registrations since 2007, the numbers in Wales fell by over 12 per cent. We cannot therefore support the Welsh Government amendment, which pretends that the Welsh Government has had a long-standing commitment to the provision of good quality affordable housing.

A gaf fi ymyrryd, os gwelwch yn dda? Beth yw'r gwahaniaeth rhwng undeb tollau a'r ardal masnach rydd?

Can I intervene, please? What's the difference between a customs union and the free trade area?
