Cyhoeddodd Llywodraeth Cymru a Llywodraeth yr Alban welliannau i’r Bil ym mis Medi, ond cafodd y rhain eu trechu yn Nhŷ’r Cyffredin yn sgil gwrthwynebiad Llywodraeth y DU iddynt. Er iddi ddweud y byddai’n gwneud hynny, nid yw’r Llywodraeth wedi cyflwyno’i gwelliannau ei hun hyd yma i ymdrin â’r pryderon ynghylch cymal 11 ac agweddau eraill ar y bil. Felly, mae Llywodraethau Cymru a’r Alban yn pwyso ar Dŷ’r Arglwyddi i ystyried cefnogi gwelliannau tebyg, os na fydd Llywodraeth y DU yn cyflwyno gwelliannau y bydd wedi cytuno arnynt gyda’r Gweinyddiaethau Datganoledig.
The Welsh and Scottish governments published amendments to the bill in September but these were defeated in the House of Commons as a result of the UK government opposition to them. Despite undertakings to do so, the government has not yet brought forward its own amendments to address the concerns about clause 11 and other aspects of the bill. The Welsh and Scottish Governments are therefore urging the House of Lords to consider supporting similar amendments, if the UK government does not bring forward its own amendments which are agreed with the Devolved Administrations.
