In a surprise result, the Conservatives won the seat from Plaid Cymru by 25 votes. The seat had been previously held by Plaid Cymru's Delme Bowen, who stood down after serving a tenure as Cardiff's Lord Mayor.[4] Bowen had been a Plaid Cymru councillor since 1995.[5]
In October 2021 Cardiff Council accepted a number of ward change proposals made by the Local Democracy and Boundary Commission for Wales. These included the merger of Creigiau/St Fagans with the Pentyrch ward to form a new ward of "Pentyrch and St Fagans". This would take effect from the 2022 council election.[6]
