Bydd yr wythnosau nesaf yn dyngedfennol o ran datblygu safbwyntiau negodi manwl y DU.  Wrth aros am ymateb pendant gan Lywodraeth y DU i'n cynigion ar gyfer ymgysylltu, bydd Prif Weinidog Cymru a minnau'n parhau i bwyso arni i weithio gyda holl lywodraethau'r DU i gytuno ar fandad sy'n diogelu buddiannau pob rhan o'r Undeb.
The coming weeks will be critical for the development of the UK’s detailed negotiating positions.  Whilst waiting for the UK Government’s substantive response to our proposals for engagement, the First Minister and I will continue to press the UK Government to work with all governments of the UK to agree a mandate that protects the interests of all parts of the Union.
