Mae amrywiaeth o ffactorau wedi cyfrannu at y sefyllfa bresennol lle mae cyfnod rhy hir o lawer wedi bod ers i’r ffiniau gael eu hadolygu, ac nid wyf am i 25 mlynedd arall fynd heibio cyn i newidiadau gael eu gwneud eto. Felly, byddaf yn rhoi cyfres reolaidd o adolygiadau ar ar waith, fydd yn ei gwneud yn ofynnol i bob ardal awdurdod lleol gael ei hadolygu o leiaf unwaith bob 10 mlynedd i sicrhau bod y gynrychiolaeth ddemocrataidd yn deg.
A variety of factors have contributed to the current situation where some boundaries have not been reviewed for far too long and I do not want to wait another 25 years before changes are made again. I will, therefore, put in place a regular rhythm of reviews which requires that each local authority area is reviewed at least once every 10 years to ensure democratic representation is fair.
