O ran y negodiadau, pwysais am fwy o rôl i'r Llywodraethau Datganoledig. Mae'r diffyg rhannu gwybodaeth a'r diffyg ymdrech gan Lywodraeth y DU i gytuno ar safbwyntiau'r DU â'r Llywodraethau Datganoledig wedi methu bodloni cylch gorchwyl Cyd-bwyllgor y Gweinidogion (Negodiadau'r UE).
On negotiations I pressed for an enhanced role for the Devolved Governments in the negotiations. The lack of information sharing and no attempt by the UK Government to agree UK positions with the Devolved Governments has failed to satisfy the terms of reference of the JMC(EN).
