Penarth Town Council came into existence in 1974[1] at the same time as local government reorganisation.

Town councillors represent Penarth's views on various committees and to wider public bodies.

[6] Sixteen councillors are elected from the four electoral wards in the town, namely: Cornerswell (4), Plymouth (4), St Augustine's (5) and Stanwell (3).

[7][8] In January 2018 the council supported recommendations that five senior councillors would receive an allowance of £500 per year.

The Conservatives increased their numbers from four to five, winning back a seat from Labour for the St Augustine's ward.
