Since 1995 Illtyd has been a county ward, electing three county councillors to Vale of Glamorgan Council unitary authority. At the 1995 and 2012 elections all three seats were won by the Labour Party, while in 1999, 2004 and 2008 all three seats were won by the Conservatives.[4]
On 4 May 2017 the Illtyd ward was regained by the Conservatives, as part of a wider success across Barry and the Vale. The three seats were won by Janice Charles, Tony Hampton and Marguerita Wright.[5]
In December 2018 one of the Conservative councillors, a former cabinet member of the council, was suspended by the Conservative Party after being charged with 10 historical sexual offences.[6]
