Mae'r Grŵp, dan gadeiryddiaeth Mr Drakeford, yn darparu cyngor i Lywodraeth Cymru ar yr heriau a’r cyfleoedd sy'n codi wrth i'r DU ymadael â'r UE. Cafodd ei sefydlu ym mis Gorffennaf 2016, yn dilyn canlyniad refferendwm yr UE ym mis Mehefin, ac fe gynhaliwyd y cyfarfod cyntaf fis Medi 2016.
The group, which is chaired by Mr Drakeford, provides advice to the Welsh Government on the challenges and opportunities arising from the UK’s withdrawal from the EU. It was established in July 2016, following the EU referendum result in June and the first meeting took place in September 2016.
