An earlier version of the Bill was introduced by the last UK Government on 20 March, but its progress was halted when Parliament was dissolved on 30 May ahead of the General Election.
Cyflwynwyd fersiwn flaenorol o'r Bil gan Lywodraeth ddiwethaf y DU ar 20 Mawrth, ond daeth taith y Bil hwnnw i ben pan gafodd Senedd y DU ei diddymu ar 30 Mai cyn yr Etholiad Cyffredinol.
