Rhaid i Lywodraeth y DU wireddu addewidion a wnaed droeon na fyddai Brexit yn arwain at golli unrhyw gyllid na phwerau datganoledig. Rhaid i Gymru beidio â cholli ceiniog o ganlyniad i adael yr UE.
The UK Government must make good on promises repeatedly made that Brexit would not mean any loss of funding or devolved powers. Wales must not be a penny worse off than it would have been within the EU.
