Er mwyn i’r Fframwaith hwn gael ei gyflawni, meddai Jeremy Miles y Gweinidog Pontio Ewropeaidd, bydd angen i Lywodraeth y Deyrnas Unedig gadw'r addewidion a wnaeth i bobl Cymru, sef na fyddwn yn colli ceiniog o fuddsoddiad a bod rhaid parchu’r setliad datganoli.
Jeremy Miles, Minister for European Transition, said that in order to deliver this framework, the UK government must keep the promises they made to the people of Wales, that we will not lose a penny of investment, and that the devolution settlement must be respected.
