Y Toriaid i gael gwared o Barnett?

'Dwi ond yn gofyn oherwydd sylwadau a wnaed gan lefarydd y Toriaid ar Ogledd Iwerddon, Owen Paterson:

...we have never said that a Conservative Government would make severe cuts to Northern Ireland’s block grant. We have said the Barnett Formula can’t last forever. Any replacement would be a needs-based formula and as Northern Ireland has substantial needs it would therefore get substantial resources. These comments prove that debate about the Barnett Formula is happening in a fact-free vacuum and we have repeatedly called on the Government to show some leadership on this issue and look at an updated needs-based assessment of how spending should be allocated across the UK.

Byddai addasu, neu gael gwared ar Barnett yn cael effaith pell gyrhaeddol ar y ffordd mae Cymru yn ogystal a Gogledd Iwerddon yn cael ei chyllido. Mae'n amlwg bod yna drafodaeth yn mynd rhagddi yn y Blaid Geidwadol.
