Dyma'r tro gyntaf i Lywodraeth Cymru cyhoeddi manylion ar gyfer costau etholiadau Cynulliad Cenedlaethol Cymru. Mae’r manylion wedi cael eu cyhoeddi o dan brosiect data agored Llywodraeth Cymru. Mae Llywodraeth Cymru yn ymrwymo i barhau i gyhoeddi’r data hwn a chaiff ei gyhoeddi cyn gynted ag y bo’n ymarferol ar ôl etholiadau'r dyfodol.
This is the first time the Welsh Government has published details of the costs of the National Assembly elections. The details are published under the Welsh Government’s open data project. The Welsh Government is committed to the continued publication of this data and will publish it as soon as is practicably possible after future elections.
