SOME OF THE KEY CONTESTS TO LOOK OUT FOR IN WALES

Blaenau Gwent has been run by a group of Independent councillors since 2017, some of whom used to be in the Labour Party. Labour is keen to take back control and might be helped by a reduction in the number of seats from 42 to 33. (3pm)

Cardiff is a key council for Labour, where the party will hope to defend its slim majority. The number of councillors is being increased slightly from 75 to 79, which might make the outcome more unpredictable. (5pm)

Flintshire sits in an area of Wales where the Conservatives did well at the 2019 General Election. The party won only six council seats in 2017 compared with Labour’s 34, so they are hoping to make an advance this year. For its part, Labour will want to remain the largest party and even win a majority, although the total number of seats is being cut from 70 to 67. (3pm)
