Gwrthododd y Canghellor adael i’r Swyddfa Cyfrifoldeb Cyllidebol ddarparu rhagolwg ariannol cyn y datganiad heddiw. Mae’r rhagolygon hyn yn cynnig arwydd hanfodol o sefyllfa ariannol y DU, ac mae peidio â gadael iddynt gael eu cyhoeddi yn anghyfrifol. Yn absenoldeb hynny, ar sail gwaith gan y Sefydliad Astudiaethau Cyllid a rhagolygon annibynnol newydd a gyhoeddwyd gan Drysorlys Ei Fawrhydi, mae gwerth cyllideb Llywodraeth Cymru dros y setliad 3 blynedd presennol hyd at £4bn yn llai mewn termau real na’r disgwyl pan wnaed y setliad hwnnw.
The Chancellor refused to let the Office for Budget Responsibility provide an economic forecast ahead of today’s statement. These forecasts are a vital indicator of the health of the UK’s finances, and it is irresponsible not to have allowed their publication. In the absence of that, based on work by the Institute for Fiscal Studies and new independent forecasts published by HM Treasury, the value of the Welsh Government’s budget over the current 3-year settlement is up to £4bn less in real terms than was expected when that settlement was reached.
