Yn ogystal â'r uchod, cynhelir adolygiad trylwyr hefyd o gynghorau tref a chymuned. Cynhelir yr adolygiad seiliedig ar dystiolaeth gan banel wedi'i gadeirio gan y Cyn-aelodau Cynulliad, Gwenda Thomas a Rhodri Glyn-Thomas. Bydd yr adolygiad yn ystyried beth sydd angen newid er mwyn i lywodraeth ar y lefel mwyaf lleol weithio'n dda a chyflawni canlyniadau.  Mae disgwyl i'r adolygiad ddechrau yn ystod yr haf, a phara am flwyddyn.
In addition to the above there will also be a root and branch review of town and community councils. The evidence-based review will be conducted by a panel chaired by former Assembly Members, Gwenda Thomas and Rhodri Glyn-Thomas. The review will consider what needs to change so that the most local level of government works well and delivers results. The review is expected to start this summer and will take a year.
