[2] A by-election was arranged for 21 February 2019[3] which was won by Andrea Gibson for Plaid Cymru by 52 votes over the Labour candidate, a swing of 18% in comparison with the May 2017 election.

[4] The Labour leader of Cardiff Council described it as " a bad day, in a week of absolute political chaos nationally"[4] (referring to the formation of The Independent Group at Westminster).

In October 2019 Councillor Gibson resigned the Plaid Cymru party whip in protest at the treatment of colleague Neil McEvoy.

At the 2004 elections, the Ely ward's Labour councillor of 30 years, Charlie Gale, stood as an Independent in an attempt to unseat (the then unpopular) Cllr Goodway.

[8] Goodway immediately stood down as Council leader, but accused senior Labour figures of conspiring against him.
