Datblygwyd y ddogfen hon ers i fersiwn fras gael ei chyhoeddi'n wreiddiol ar 14 Tachwedd, ond nid yw'n llwyddo o hyd i roi sicrwydd clir o berthynas yn y dyfodol â 27 yr UE a fyddai'n diogelu buddiannau Cymru a'r DU yn gyfan. Nid yw'n ddigonol o hyd ac, fel yr amlinellir isod, nid yw'n darparu'r sylfaen gywir ar gyfer perthynas y DU â'r UE yn y dyfodol.
Although this document has been developed since an outline was published on 14 November, it remains the case that it fails to provide clear guarantees about a future relationship with the EU27 that would protect the interests of Wales and the UK as a whole. It remains inadequate and, as set out below, does not provide the right basis for the UK’s future relationship with the EU.
