Mae Llywodraeth y DU wedi rhoi Cymru dan anfantais systematig mewn meysydd cysylltedd y mae wedi’u cadw’n ôl – rheilffyrdd, band eang a hedfan.  Mae wedi bod yn ystyfnig a gwrthod datganoli’r pwerau hyn. Byddai gwneud hynny’n rhoi’r awenau i eraill sydd â mwy o ddiddordeb ac ymrwymiad i wella pethau.  Mae’r Adolygiad o Gysylltedd yr Undeb yn gyfle i Lywodraeth y DU feddwl am ei hesgeulustod, a chanolbwyntio ar wneud pethau’n iawn.
The UK Government has systematically failed Wales in areas of connectivity it has reserved to itself – rail, broadband and aviation.  It has stubbornly failed to devolve these powers to let others with a greater interest and commitment to improvement take over.  The Union Connectivity Review is an opportunity for the UK Government to reflect on its neglect, and focus on putting these areas right.
