Yn fyr, diolch. Mae'r sector llywodraeth leol yr wyf i'n ymgysylltu ag ef yng Nghymru wedi bod yn dweud wrthyf ers tro byd am y gost ychwanegol gronnol y bu'n rhaid iddyn nhw ei hysgwyddo o ganlyniad i bolisïau neu ddeddfwriaeth Llywodraeth Cymru heb eu hariannu neu heb eu hariannu'n ddigonol. Nid sylw ynghylch rhinwedd neu ddiffyg rhinwedd y ddeddfwriaeth yw hynny; mae'n ymwneud â'u gallu i gyflawni hynny heb beryglu gwasanaethau eraill. Cyfeiriodd y Gweinidog, yng Nghyfnod 2, fel y dywedais i, wrth iddi wrthod gwelliant cyfatebol, at y cyllid y mae awdurdodau lleol eisoes yn ei gael neu'n ei gael mewn grantiau penodol. Pe byddai hi wedi dweud wedyn y byddem yn archwilio methodoleg i sicrhau bod cynghorau yn cael iawndal llawn am gost net wirioneddol gweithredu'r mesurau hyn, ni fyddem wedi cyflwyno'r gwelliant hwn. Ond nid dyna sut yr ydym ni'n cofio hyn yn datblygu. Mae hwn yn ddarn mawr o ddeddfwriaeth llywodraeth leol a fydd â chostau cychwynnol sylweddol ac o bosibl costau tymor hwy i'r teulu llywodraeth leol ledled Cymru, a dylai ein gwelliannau sefyll yn unol â hynny.

Briefly, thank you. The local government sector I engage with in Wales has long been telling me about the cumulative additional cost they've had to absorb in consequence of unfunded or underfunded Welsh Government policies or legislation. That is not a comment on the merit or otherwise of the legislation; it is on their ability to deliver that without compromising other services. The Minister, at Stage 2, as I stated, referred in her rejection of an equivalent amendment to the funding that local authorities already receive or receive in specific grants. Had she then said that we would examine a methodology to ensure that councils are fully compensated for the actual net cost of implementing these measures, we wouldn't have put this amendment down. But that's not how we recall this having played out. This is a major piece of local government legislation that will have significant initial costs and possibly longer term costs for the local government family across Wales, and our amendments should stand accordingly.

Daw hyn â ni at yr eitem nesaf, sef y cynnig i amrywio'r drefn ystyried ar gyfer gwelliannau ar Gyfnod 3 y Bil Rhentu Cartrefi (Ffioedd etc.) (Cymru). Rydw i'n galw ar y Gweinidog Tai a Llywodraeth Leol, Julie James.

That brings us to our next item, which is a motion to vary the order of consideration of Stage 3 amendments to the Renting Homes (Fees etc.) (Wales) Bill. I call on the Minister for Housing and Local Government, Julie James.

Fe gymeraf ymyriad mewn munud, Lee, ond gadewch i mi wneud ychydig o gynnydd, os caf. Maent ill dau'n gweithio ar hyn yn ddiflino gyda'r Llywodraeth i wneud yn siŵr fod yna ddyfodol, fel y mae Llywodraeth y DU wedi ymrwymo iddo, i ddiwydiant dur Prydain, y nodwyd ei fod yn rhan annatod o'r strategaeth weithgynhyrchu a'r strategaeth ddiwydiannol y mae Theresa May wedi'u rhoi wrth wraidd polisi Llywodraeth y DU. Fe gymeraf yr ymyriad.

I'll take the intervention in a minute, Lee, but let me make a little progress, if I may. They are both working on this tirelessly with the Government to make sure that there is a future, as has been committed to by the UK Government, for the British steel industry, which is identified as integral to the manufacturing strategy and the industrial strategy that Theresa May has put at the heart of UK Government policy. I'll take the intervention.

Diolch, Llywydd. Prif Weinidog, pryd fyddwch chi'n gwneud penderfyniad ynghylch dyfodol ffordd liniaru'r M4, o gofio bod adroddiad yr ymchwiliad ar eich desg erbyn hyn?

Diolch, Llywydd. First Minister, when will you make a decision about the future of the M4 relief road, given that the inquiry's report is now on your desk?

croeso mawr ichi i'r Cynulliad -

a warm welcome to you to the National Assembly -
