In May 2021 Cllr Mustoe introduced himself as the new divisional member for Mevagissey and St Austell Bay and thanked everyone who voted for him. He said that he has been a Cornwall Councillor for Mevagissey division for 7 years and looks forward to getting involved in community and parish council initiatives. Cllr Mustoe said that because St Austell Bay Parish Council's monthly meetings are held on the same evening as those of Mevagissey Parish Council, he will be alternating between the meetings.
