Cadarnhaodd Gweinidogion y DU eu bwriad i gyflwyno eu gwelliannau eu hunain yn Nhŷ'r Arglwyddi er mwyn dangos cynnydd a gweld teimladau'r Tŷ yn ystod y Cyfnod Pwyllgor, ac mae’r rhain bellach wedi eu cyflwyno. Fodd bynnag, fy nealltwriaeth glir i oedd nad oedd y Llywodraeth yn bwriadu pwyso am bleidlais dros welliannau o'r fath, ac y byddai cyfle i gael trafodaeth bellach cyn cynhyrchu gwelliant terfynol ar gyfer Cyfnod Adrodd Tŷ'r Arglwyddi. Mae Llywodraeth Cymru wedi dweud yn glir y byddai wedi bod yn llawer iawn gwell cytuno ar welliannau rhwng y tair Llywodraeth cyn hyn. Fodd bynnag, yn fy marn i, nid yw gwelliant Llywodraeth y DU nawr yn gwneud unrhyw beth ond diogelu ei sefyllfa, fel opsiwn wrth gefn, yn yr un modd ag y mae'n deddfwriaeth Parhad ni yn ei wneud i Lywodraeth Cymru a'r Cynulliad Cenedlaethol.
UK Ministers confirmed that they would be introducing their own amendment(s) in the House of Lords in order to show progress and to test the mood of the House at Committee stage, these have now been tabled. However, I was left with a clear understanding that it would not be the Government’s intention to press such amendments to a vote, and that there would be opportunities for further discussion before an amendment in final form was produced for Lords Report stage. The Welsh Government has been very clear it would have been far preferable to have had amendments already agreed between the three Governments before now. However, in my view, a UK Government amendment at this stage does no more than protect its position, as a fall-back option, in much the same way as our Continuity legislation does for the Welsh Government and National Assembly.
