Mae Llywodraeth Cymru wedi bod yn ystyried y ffordd ymlaen. Wrth wneud hynny, rydym wedi ceisio cael mesurau diogelu clir iawn na fyddem, wrth ymuno â deddfwriaeth y DU, yn llyffetheirio ein gallu i gyflawni'r canlyniadau polisi pwysig a geisiwn drwy Fil Partneriaeth Gymdeithasol a Chaffael Cyhoeddus (Cymru). Dyna pam yr ydym wedi ceisio cael gwarantau ysgrifenedig gan Lywodraeth y DU ar hyd y trywydd hwn, rhai yr wyf yn falch o ddweud eu bod bellach wedi'u cael gan Swyddfa’r Cabinet yn Llywodraeth y DU.
The Welsh Government has considered the way forward. In doing that we have sought very clear safeguards that in joining UK legislation we would not fetter our ability to achieve the important policy outcomes we seek through the Social Partnership and Public Procurement (Wales) Bill. That is why we have sought written guarantees from the UK Government along these lines, ones I am pleased to say that have now been received from the UK Cabinet Office.
