The Bill as drafted includes concurrent powers that could be exercised by UK Government Ministers in devolved areas without the consent of the Welsh Ministers.
Mae’r Bil, fel y’i drafftiwyd, yn cynnwys pwerau cydredol y gellid eu harfer gan Weinidogion Llywodraeth y DU mewn meysydd datganoledig heb gydsyniad Gweinidogion Cymru.
