Mae’r achos amlinellol ar gyfer y DU, fodd bynnag, yn ddechrau rhesymol ar gyfer y trafodaethau.  Nid yw’n gwneud consesiynau di-angen, ond mae modd ei ddehongli sawl ffordd fodd bynnag.  Mae’n rhaid inni bellach fod yn rhan lawn o’r trafodaethau i sicrhau bod buddiannau Cymru yn cael eu gwarchod a’r addewidion sy’n cael eu gwneud am ein GIG, safonau bwyd a meysydd eraill yn cael eu cadw.
The outline case for the US is, nevertheless, a reasonable starting point for negotiations. It does not make unnecessary concessions, however it is very open to interpretation. We now need to be fully involved in negotiations to ensure Welsh interests are protected and promises made about our NHS, food standards and other areas are honoured.
