**This does not affect Senedd, local council elections and Town/Community elections in Wales as these elections are the responsibility of Welsh Government.
**Nid yw'n effeithio ar etholiadau'r Senedd, cynghorau lleol a chynghorau tref/cymuned yng Nghymru gan mai Llywodraeth Cymru sy'n gyfrifol am yr etholiadau hyn.
