Brif Weinidog, bob bore Sadwrn am 9 a.m. ledled Cymru, mae miloedd o bobl yn cymryd rhan mewn parkruns. Fe'u harweinir gan wirfoddolwyr, maen nhw'n cael eu hamseru a gall pobl fonitro eu cynnydd wrth iddyn nhw, gobeithio, wella eu hamseroedd dros y misoedd ac, yn wir, y blynyddoedd. Yng Nghasnewydd, ychwanegwyd at parkrun presennol Tŷ Tredegar yn ddiweddar gyda parkrun trefol canol y ddinas ar hyd glan yr afon. Cymerais ran mewn digwyddiadau diweddar a mwynheais y buddion fel y mae cymaint o bobl eraill yn ei wneud, Brif Weinidog, er bod fy llawenydd ynghylch cael amser personol gorau wedi cael ei leihau ychydig pan ddywedodd y gŵr a orffennodd o fy mlaen ei fod newydd gael clun newydd. [Chwerthin.] Ond, serch hynny, maen nhw'n ddigwyddiadau pwysig iawn ac rwyf wedi rhedeg amser gorau personol. Brif Weinidog, a wnewch chi ymuno â mi i gydnabod a thalu teyrnged i bwysigrwydd ac arwyddocâd y parkruns hyn, sydd yn gwneud cyfraniad cynyddol i gael poblogaeth fwy egnïol yn gorfforol ar hyd a lled Cymru gyfan?

First Minister, every Saturday morning at 9 a.m. right across Wales, thousands of people take part in parkruns. They're volunteer led, they're timed and people are able to chart their progress as they, hopefully, improve their times over the months and, indeed, the years. In Newport, the existing Tredegar House parkrun has just been added to with a city centre urban parkrun along the riverside. I took part in recent events and enjoyed the benefits as so many others do, First Minister, although my joy in setting a personal best was somewhat reduced when the man who finished in front of me confided that he'd just had a hip replacement. [Laughter.] But, nonetheless, they're very important events and I have set a personal best. First Minister, will you join me in recognising and paying tribute to the importance and significance of these parkruns, which are making a growing contribution to getting a more physically active population right across the length and breadth of Wales?

Ac nid oes amheuaeth y byddwch yn gwneud cystal ag y gwnaethoch yn y gorffennol.

And no doubt you'll do as well as you have in the past.

Ddydd Llun gŵyl y banc, fe gyhoeddodd y Gweinidog addysg gyllideb o dros £3 miliwn ar gyfer darparu 1,800 o beiriannau diheintio osôn yn ein hysgolion, colegau a phrifysgolion. Ddeuddydd yn ddiweddarach, yn dilyn galwadau am sicrwydd ynghylch diogelwch gan Blaid Cymru ac eraill, fe ddaeth hi i'r amlwg bod Gweinidogion wedi gwneud tro pedol ar y penderfyniad. Fedrwch chi egluro'r broses a arweiniodd at y penderfyniad dadleuol i gaffael a defnyddio'r peiriannau, a hefyd beth oedd tu ôl i'r penderfyniad i beidio â phrynu'r peiriannau? Ydych chi'n cytuno efo fi y dylai'r Llywodraeth gynnal adolygiad i'r broses o wneud y penderfyniadau yma ar y peiriannau osôn, ac ydy'r Llywodraeth rŵan yn barod i roi ffocws ar lanhau'r awyr, yn cynnwys darparu peiriannau ffiltro awyr sy'n cael eu defnyddio'n helaeth mewn gwledydd eraill erbyn hyn?

On bank holiday Monday, the Minister for education announced a budget of over £3 million for the provision of 1,800 ozone disinfectant machines in our schools, colleges and universities. Two days later, following calls for assurances on the safety of the equipment from Plaid Cymru and others, it became apparent that Ministers had carried out a u-turn on that decision. Can you explain the process that led to that contentious decision to procure and use those machines, and what was behind the decision not to purchase those? Now, would you agree with me that the Government should conduct a review of the process of making these decisions on ozone equipment, and will the Government now provide a focus on ventilation, including providing air-filtration machines used a great deal in other nations?

Wel, fel y gŵyr Nick Ramsay, drwy'r briff y mae wedi'i gael fel rhan o waith y Pwyllgor Cyfrifon Cyhoeddus, anghytundeb technegol yw hwn rhwng Llywodraeth Cymru a'r archwilydd o ran sut y dylid dosbarthu cyllid ar gyfer eleni, yn yr ystyr fod y cyllid wedi'i gyhoeddi a'i ddosbarthu mewn gwahanol flynyddoedd o bosibl. Felly, mae'n anghytundeb o ran sut y dylid codio pethau. Ond mae'n rhaid i mi ddweud, nid ni yw'r unig rai yn y sefyllfa hon. Credaf fod pob un o'r pedair Llywodraeth ledled y DU yn wynebu'r un penderfyniad. Ac yn sicr, nid ydym yn difaru gwneud y cyhoeddiad cynnar hwnnw ynghylch cymorth i fusnesau, fel y gallent gynllunio a pharatoi wrth i'r cyfyngiadau symud cyntaf ddod i rym yn ôl ym mis Mawrth.

Well, as Nick Ramsay will know, through the briefing he's had as part of the Public Accounts Committee's work, this is a technical disagreement between the Welsh Government and the auditor in terms of how funding should be classified for this year, in the sense that funding was announced and when it went out the door was potentially across years. So, it is a disagreement in terms of how things should be coded. But, I have to say, we're not the only ones in this position. I think all four Governments across the UK are facing the same decision. And, absolutely, we don't regret making that early announcement of support for businesses, so that they could plan and prepare as we entered the original lockdown back in March.

Mae gennym lwybrau drwy awdurdodau lleol lle y mae cyfleoedd i siarad â swyddogion atal digartrefedd mewn awdurdodau ledled Cymru. Mae gennym gydnabyddiaeth dda iawn ar ostyngiad o 63 y cant mewn ffigurau digartrefedd yng Nghymru.

We have pathways through local authorities where there are opportunities to speak with anti-homelessness officers in authorities across Wales. We have a very good recognition in a 63 per cent reduction in homelessness figures in Wales.
