English: Can I thank you, Presiding Officer, for accepting this topical question? And it would have been helpful, I think, if the Minister had brought an oral rather than a written statement on this matter. Of course, I read your statement today, Minister, and, as far as I'm concerned, from reading the statement we are going back to square one, with another expert commission appointed to look at alternatives to the Welsh Government's own proposals after, as we learned from the statement today, £114 million of public money being spent or wasted on developing proposals for a two-year long independent public inquiry. I would agree with the comments in your statement today, Minister, that the Welsh Government does need to find a solution quickly, so I do have a number of questions. What will be the timetable for the expert commission to report? What budget will you be allocating specifically for the works of the expert commission? Who will appoint the members of this commission, and how long will this recruitment process take? And will you commit to abiding by the commission's conclusions or will there be capacity for this expert commission's reporting to be disregarded? Minister, you've told this Assembly that it is essential that we plan transport holistically and that we do not see transport modes in isolation, and you went on to say that, if you were to maximise the capacity on the metro, the maximum you could remove from the M4 was only 4 per cent. Do you think that any alternative proposals you make will remove more than 4 per cent? The First Minister pointed out yesterday that a series of fast-tracked targeted interventions to alleviate congestion on the M4 will be made in the interim period, and your statement today has alluded to that. If the Minister thinks that short-term measures are effective, why have they not previously been implemented when they could have been in place years ago? And finally, Presiding Officer, the Minister has previously said, and I quote here, that piecemeal and useful improvements have been undertaken over time, but they've only postponed the issue - they've only postponed the issue - this piece of infrastructure needs a major long-term upgrade. So can I ask: does the Minister now believe that such a major infrastructure upgrade on the M4 will no longer be needed?
Welsh: A gaf fi ddiolch i chi, Lywydd, am dderbyn y cwestiwn amserol hwn? A byddai wedi bod o gymorth, rwy'n credu, pe bai'r Gweinidog wedi cyflwyno datganiad llafar yn hytrach na datganiad ysgrifenedig ar y mater hwn. Wrth gwrs, darllenais eich datganiad heddiw, Weinidog, ac o'm safbwynt i, o ddarllen y datganiad, rydym yn mynd yn ôl i'r cychwyn, gyda chomisiwn arbenigol arall wedi'i benodi i edrych ar gynigion eraill yn lle cynigion Llywodraeth Cymru ei hun ar ôl i £114 miliwn, fel y clywsom o'r datganiad heddiw, o arian cyhoeddus gael ei wario neu ei wastraffu ar ddatblygu cynigion ar gyfer ymchwiliad cyhoeddus annibynnol dros gyfnod o ddwy flynedd. Buaswn yn cytuno â'r sylwadau yn eich datganiad heddiw, Weinidog, fod angen i Lywodraeth Cymru ddod o hyd i ateb yn gyflym, felly mae gennyf nifer o gwestiynau. Beth fydd yr amserlen i'r comisiwn arbenigol gyflwyno'u hadroddiad? Pa gyllideb y byddwch yn ei dyrannu'n benodol ar gyfer gwaith y comisiwn arbenigol? Pwy fydd yn penodi aelodau'r comisiwn hwn, a faint o amser fydd y broses recriwtio yn ei gymryd? Ac a wnewch chi ymrwymo i lynu at gasgliadau'r comisiwn neu a fydd modd diystyru adroddiadau'r comisiwn arbenigol hwn? Weinidog, rydych wedi dweud wrth y Cynulliad hwn ei bod yn hanfodol ein bod yn cynllunio trafnidiaeth yn gyfannol ac nad ydym yn edrych ar foddau trafnidiaeth ar eu pen eu hunain, ac aethoch ymlaen i ddweud, pe baech yn gwneud y mwyaf o'r capasiti ar y metro, mai'r uchafswm y gallech ei dynnu oddi ar yr M4 oedd 4 y cant yn unig. A ydych yn credu y bydd unrhyw gynigion amgen a wnewch yn tynnu mwy na 4 y cant oddi arni? Ddoe, dywedodd y Prif Weinidog y bydd cyfres o ymyriadau cyflym wedi'u targedu yn cael eu gwneud yn y cyfamser i liniaru tagfeydd ar y M4, ac mae eich datganiad heddiw wedi cyfeirio at hynny. Os yw'r Gweinidog yn credu bod mesurau tymor byr yn effeithiol, pam nad ydynt wedi cael eu gweithredu yn y gorffennol pan ellid bod wedi eu rhoi ar waith flynyddoedd yn ôl? Ac yn olaf, Lywydd, mae'r Gweinidog wedi dweud o'r blaen, ac rwy'n dyfynnu yma, fod gwelliannau tameidiog a defnyddiol wedi cael eu gwneud dros amser, ond nid ydynt ond wedi gohirio'r mater - nid ydynt ond wedi gohirio'r mater - mae angen gwaith uwchraddio helaeth ar y darn hwn o seilwaith yn hirdymor. Felly a gaf fi ofyn: a yw'r Gweinidog bellach yn credu na fydd angen gwaith uwchraddio mor helaeth ar seilwaith yr M4 mwyach?
