English: I do think how we control the supply of land is a really important issue; I'm not convinced this is going to be a particularly productive way to do that, but I'm certainly open to evidence. There's a real public interest here - the greatest windfall, I should say to you, Minister, of course, is when land is zoned for building when it had a previous use, especially if the previous use was agricultural. And, you know, there is a real - . The biggest factor in high house prices is actually the price of land. So, there is a real public interest to have a more equitable system over some of these forces, which is why I quite like Oliver Letwin's more holistic examination of this particular area. But 7,600 homes could be built if all the current land plots were used and that's over a year's supply of housing at our current rate that we need to increase that. I think a couple of Members - Neil Hamilton mentioned it directly - . We need a system, if we're going to go down this track, that is flexible enough to take account of market conditions because some people could get penalised in a downturn when they've got every intention, actually, of using the land productively, but, for whatever reason, cannot get all the capital together to undertake the building programme. And so I think (1) you could set the bar quite high; you could say that the tax only gets applied after 18 months or two years - you could do that, and that would give you time to assess market conditions - or, if you're going to do it after a year, have certain ways of being flexible, should market conditions require that. So, I think it is worth us looking at this, but, as I said, I'd like to reserve my position until we see further evidence. And, as you said, the model is used in some other countries, so I think a further examination of the situation there - particularly over how it does produce a more effective market, because I think that's really, really important. We could end up undermining the market at certain times if we're not careful.
Welsh: Rwyf i o'r farn fod y dull o reoli cyflenwad tir yn fater pwysig iawn; nid wyf wedi fy argyhoeddi y bydd hon yn ffordd arbennig o gynhyrchiol o wneud hynny, ond rwy'n agored i dystiolaeth yn sicr. Mae diddordeb cyhoeddus gwirioneddol yma - yr arian annisgwyl mwyaf, dylwn ddweud wrthych chi, Gweinidog, wrth gwrs, yw pan gaiff tir ei roi ar gyfer parthau i adeiladu pan fu defnydd blaenorol iddo, yn enwedig pan fyddai'r defnydd blaenorol yn amaethyddol. A, wyddoch chi, mae yna wir - . Y ffactor mwyaf gyda phrisiau tai uchel yw pris y tir mewn gwirionedd. Felly, mae diddordeb cyhoeddus gwirioneddol o ran cael system decach dros rai o'r grymoedd hyn. A dyna pam fy mod i'n eithaf hoffi archwiliad mwy cyfannol Oliver Letwin o'r maes penodol hwn. Ond fe ellid adeiladu 7,600 o gartrefi pe defnyddiwyd pob un o'r lleiniau tir presennol, ac mae hynny'n dros flwyddyn o'r cyflenwad tai yn ôl y gyfradd gyfredol y mae ei hangen arnom i gynyddu hynny. Credaf fod un neu ddau o'r Aelodau - soniodd Neil Hamilton am hyn yn uniongyrchol - . Mae angen system arnom ni, os ydym am fynd ar hyd y trywydd hwn, sydd yn ddigon hyblyg i ystyried amodau'r farchnad oherwydd gallai rhai pobl gael eu cosbi yn ystod cyfnod o gwymp pan maent yn llwyr fwriadu defnyddio tir mewn ffordd gynhyrchiol, mewn gwirionedd, ond, am ba reswm bynnag, nad oes modd iddynt gael yr holl gyfalaf ynghyd i ymgymryd â rhaglen adeiladu. Ac felly rwyf i o'r farn (1) y gallech chi osod y bar yn uchel; y gallech chi ddweud na fyddai'r dreth ond yn gymwys ar ôl 18 mis neu ddwy flynedd - fe allech chi wneud hynny, a byddai hynny'n rhoi amser ichi asesu cyflwr y farchnad - neu, pe byddech chi'n gwneud hynny ar ôl blwyddyn, bod gennych rai ffyrdd o fod yn hyblyg, pe byddai amodau'r farchnad yn gofyn am hynny. Felly, credaf ei bod yn werth inni edrych ar hyn, ond, fel y dywedais, hoffwn ymatal rhag mynegi fy safbwynt i hyd nes y gwelwn dystiolaeth bellach. Ac, fel y dywedasoch, mae'r patrwm yn cael ei ddefnyddio mewn rhai gwledydd eraill, felly mae archwiliad pellach ar y sefyllfa yn y fan honno - yn arbennig o ran sut mae'n esgor ar farchnad fwy effeithiol, oherwydd credaf fod hynny'n wirioneddol bwysig. Yn y pen draw gallem danseilio'r farchnad ar rai adegau os nad ydym yn ofalus.
