Dros y tair blynedd a hanner diwethaf, mae Llywodraeth Cymru wedi manteisio ar bob cyfle i roi gwybod i Lywodraeth y Deyrnas Unedig beth yw blaenoriaethau Cymru o ran perthynas y DU â'r Undeb Ewropeaidd yn y dyfodol. Rydym wedi ceisio bod yn adeiladol, gan obeithio dod i gytundeb gyda Llywodraeth y DU, a galluogi'r DU i sicrhau sefyllfa o undod a nerth wrth negodi â'r UE.
Over the last three and a half years the Welsh Governmenthas taken every opportunity to set out Welsh priorities for the UK’s future relationship with the EU to the UK government. We have looked to be constructive, hoping to get agreement with the UK government, enabling the UK to enter the negotiations with the EU from a position of unity and strength.
