“Dydyn ni ddim wedi cael y cyfle i ddarllen Papur Gwyn Llywodraeth y DU ar ei safbwynt negodi â’r UE cyn cyfarfod Cyd-bwyllgor y Gweinidogion (Negodiadau’r UE) heddiw, felly bydd yn amhosib inni wneud y math o gyfraniad ystyriol, ar sail tystiolaeth, sy’n hanfodol yn ein barn ni. Mae hyn yn amlwg yn mynd yn groes i gylch gorchwyl y Cyd-bwyllgor, sy’n nodi bod gofyn i’r Pwyllgor geisio sicrhau cytundeb ar safbwynt negodi Llywodraeth y DU. Mae’n golygu na fydd safbwynt Llywodraeth y DU mor gynhwysfawr ag y dylai fod o ran manylion am gyfrifoldebau datganoledig, wrth i gam nesaf allweddol y negodiadau gychwyn.”
“We have not had the opportunity to read the UK government’s White Paper on its negotiating position with the EU ahead of today’s Joint Ministerial Committee (EU Negotiations), so it will be impossible for us to make the sort of considered contribution, based on evidence, which we think is essential. This is a clear breach of the JMC (EN)’s terms of reference, which require the Committee to try to seek agreement on the negotiation position of the UK government. It means that the UK government’s position will not be as informed about devolved responsibilities as it needs to be, as negotiations move into their vital next phase."
