Conwy County Borough
Llanrwst is now divided into two electoral wards, Gower and Crwst, each electing a councillor to Conwy County Borough Council. In 2017, Plaid Cymru's Aaron Wynne was elected to the Crwst ward on Conwy County Borough Council at 20 years of age, making him Wales's youngest county councillor and Conwy County Borough Council’s youngest ever elected member. The town also elects councillors to Llanrwst Town Council.
