Llywodraeth y DU sy'n gyfrifol am y newidiadau hyn a rhaid iddi sicrhau eu bod yn cael eu hariannu'n llawn. Mae Llywodraeth Cymru'n ysgrifennu, ar y cyd â'r gweinyddiaethau datganoledig eraill, i alw ar i'r newidiadau pensiwn hyn gael eu hariannu gan Drysorlys Ei Mawrhydi a hynny ar frys.
The UK Government is responsible for these changes and must ensure they are fully funded. The Welsh Government is writing, jointly with the other devolved administrations, to call for these pension changes to be fully funded as a matter of urgency by HM Treasury.
