Roedd hwnna'n ddechrau da, onid oedd? Rydw i am ddechrau, os caf i, efo'r cwestiynau rydw i'n meddwl bod y rhan fwyaf o bobl yn mynd i fod eisiau chwilio am yr ateb iddyn nhw rŵan, sef pryd ydyn ni'n mynd i wybod ydy'r firebreak wedi gweithio. Mae hynna'n gwestiwn eithaf amlwg. Mi rydym ni'n aros am ddiweddariad ar senarios, reasonable worst-case scenario Prifysgol Abertawe. Pryd gawn ni hwnnw, yn gyntaf, er mwyn gwybod beth oedd impact y clo dros dro?

That was a good start, wasn't it? I want to start, if I may, with the questions that everyone will want the answer to, namely when we'll know whether the firebreak has succeeded. It's an obvious question, isn't it? We are waiting for an update on the reasonable worst-case scenario modelling by Swansea University. So, when will we receive that, so we can know what the impact of the firebreak was?

Dyna fe, diolch yn fawr iawn i chi - croeso. Mi awn ni'n syth i gwestiynau, os ydy hynny'n iawn. Jest un cwestiwn bach syml ar y dechrau, efallai, jest i gadarnhau: a ydych chi'n bwriadu cyflwyno mwy o welliannau, efallai, nag ŷch chi wedi'u rhannu â ni i'r Bil yma? Os ŷch chi, a ydych chi'n mynd i wneud unrhyw waith costio arnyn nhw?

Okay, thank you - welcome. We'll go straight to questions, if that's okay. Just one simple question at the outset, just to confirm: are you intending to bring forward any more amendments than those that you've shared with us for this Bill? If you are, have you done any costings work on them?

Diolch, Llywydd. Cynigiaf y pedair cyfres o gynigion sy'n cynnwys rheoliadau ger ein bron heddiw yn ffurfiol, a gofynnaf i Aelodau eu cefnogi. Cyflwynwyd y rheoliadau hyn unwaith eto o dan Ddeddf Iechyd y Cyhoedd (Rheoli Clefydau) 1984 drwy ein gweithdrefnau brys i gefnogi sut yr ydym ni'n mynd ati ar hyn o bryd i ymdrin â'r coronafeirws. Fe ŵyr aelodau bod Llywodraeth Cymru yn mynd i'r afael â'n strategaeth i ymdrin â'r coronafeirws mewn modd pwyllog sy'n seiliedig ar dystiolaeth, gan gynnwys drwy'r gofyniad ffurfiol i adolygu'r angen am unrhyw un o'r gofynion a'r rheoliadau hyn, a'u cymesuredd, bob 21 diwrnod.

Thank you, Llywydd. I formally move the four sets of motions containing regulations before us today, and ask Members to support them. These regulations were again introduced under the Public Health (Control of Disease) Act 1984 through our emergency procedures to support our ongoing approach to tackling coronavirus. Members will know that the Welsh Government takes a careful and evidence-based approach to our strategy for dealing with coronavirus, including through the formal requirement to review the need for any of these requirements and regulations, and their proportionality, every 21 days.

Rwy'n credu bod y gwaith y maen nhw wedi ei wneud yn ddefnyddiol iawn ac mae'n ychwanegiad defnyddiol iawn at ein gwybodaeth bresennol yn y maes hwn. Byddwn, wrth gwrs, yn ystyried yr argymhellion yn ofalus yng ngoleuni ein mentrau presennol i gefnogi canol trefi.

I think the work they've done is very useful and it's a very useful addition to our existing knowledge in this area. We will, of course, consider the recommendations carefully in light of our current initiatives to support town centres.
