Yng Nghymru, mae proses wedi bod ar waith dros y pedair blynedd diwethaf, i edrych ar wardiau etholiadol llywodraeth leol yng Nghymru – ar gyfer y 22 prif awdurdod lleol. Gall hyn hefyd gael effaith ganlyniadol ar ffiniau cynghorau tref a chymuned. Fodd bynnag, mae honno’n broses ar wahân ac yn wahanol i'r adolygiad presennol o ffiniau etholiadol Senedd y DU.
In Wales, a process has been underway over the last four years, to look at the electoral wards for local government in Wales – for the 22 principal local authorities. This process can have consequential implications for town and community council boundaries. However, this process is separate and distinct to the current review of UK Parliamentary boundaries.
