Cynhwysir pwerau i hwyluso uno gwirfoddol rhwng prif gynghorau ac ailstrwythuro prif ardal yn y Bil, os bydd eu hangen.
The Bill will introduce a new system for improving performance and governance based on self-assessment and peer review, including the consolidation of the Welsh Ministers’ support and intervention powers. Powers to facilitate voluntary mergers of principal councils and restructuring a principal area are included in the Bill, should these be required.
