Rwyf wedi mynegi fy mhryderon am y mater hwn ar sawl achlysur.  Mae’n siomedig bod y pryderon hyn wedi’u gwireddu a byddaf yn ysgrifennu at Lywodraeth y DU i dynnu sylw at oblygiadau eu gweithredoedd.
I have expressed my concerns about this matter on a number of occasions. It is disappointing that those concerns have become reality and I will be writing to the UK government to spell out the implications of their actions.
