English: Yes. It is important to have a definition. That is, if you have a planning regime where you have to make a planning application to change from one category to another, then you have to have a very clear definition of what a second home is, and so on. It isn't as easy as that. That's why, perhaps, we need to have this discussion and debate, particularly with regard to planning. There are several categories, aren't there? There is a second home that isn't let as holiday accommodation. There are homes that are let as short-term lets without any kind of regulation, through Airbnb, for example, and the growth in that direction has been extraordinary, truth be told. And, of course, there are holiday homes that have had permission, for example, to turn outbuildings into homes to be holiday accommodation, and there are planning restrictions on them and so on. And I believe that holiday accommodation is clear; it's part of the planning regime, but in my opinion, they don't detract from the housing stock. The difficult one, of course, is if you define a primary residence as, well, let's say, somebody has to live there for a number of days in a year - yes, the number of days would be the measure, I would think - it's difficult to police that, isn't it? It's very difficult for any planning authority to gather evidence of how many days in a year a property is used or not. So, it is an important area to consider, and I think that that discussion is ongoing. But we do have to have that clear definition, I believe. I believe I've seen a definition of a primary residence as where one person lives continually. And that could be year-round, rather than somebody having two properties, and that they then select which one is their primary residence for taxation purposes and so on. Let's be clear, you have to live there all year long. That could be a definition, but that's something to discuss.
Welsh: Ie. Mae'n bwysig cael diffiniad. Hynny ydy, os oes gennym ni drefn cynllunio lle rydyn ni'n gorfod gwneud cais cynllunio i newid o un categori i'r llall, yna mae'n rhaid cael diffiniad clir iawn o beth yw ail gartref ac yn y blaen. Dydy o ddim mor rhwydd â hynny. Dyna pam, hwyrach, y gallai fod angen i ni gael y drafodaeth yna, yn arbennig yn y maes cynllunio. Mae yna sawl categori, onid oes? Mae yna ail gartref sydd ddim yn cael ei osod, mae'n bosib. Mae yna gartrefi sy'n cael eu gosod tymor byr heb unrhyw fath o reolaeth, trwy Airbnb, ac mae'r cynnydd yn y rheini'n rhyfeddol a dweud y gwir. Ac, wrth gwrs, mae yna lety gwyliau sydd wedi cael caniatâd, er enghraifft, i drosi beudai, neu rywbeth felly, i fod yn llety gwyliau, ac mae yna gyfyngiadau cynllunio arnyn nhw beth bynnag. Rŵan, dwi'n credu bod y llety gwyliau yn glir allan o'r drefn; maen nhw'n rhan o'r drefn gynllunio, ac maen nhw'n rhan o'r - . Ond dydyn nhw ddim, yn fy marn i, yn tynnu allan o'r stoc dai. Yr un anodd ydy, wrth gwrs, os ydych chi'n diffinio prif gartref fel, dywedwn ni, fod rhaid i rywun fyw yna am nifer o ddyddiau'r flwyddyn neu - ie, nifer o ddyddiau fuasai'r mesur mae'n debyg - mae hi'n anodd plismona hynny, onid ydy? Mae'n anodd iawn i unrhyw awdurdod cynllunio gael tystiolaeth o'r union faint o ddyddiau mewn blwyddyn mae'n cael ei ddefnyddio neu ddim. Felly, mae o'n faes pwysig, a dwi'n credu bod y drafodaeth yna'n parhau. A dwi'n meddwl ein bod ni - . Ond mae'n rhaid inni gael y diffiniad yna. Dwi'n credu fy mod i wedi gweld yn rhywle lle mae'r diffiniad o brif gartref ydy lle mae rhywun, un person, yn byw ynddo fo yn barhaol, felly. Mi allai hynny fod trwy'r flwyddyn, yn hytrach na bod rhywun yn cael dau eiddo, un i ffwrdd, ac yn dewis pa un sydd yn brif gartref, er mwyn osgoi trethiant ac yn y blaen. Wel, gadewch inni fod yn glir, mae'n rhaid i chi fyw yna drwy'r flwyddyn. Ond mae hwnna'n fater i'w drafod, dwi'n credu.
