Labour have won the Woolston by-election with a reduced majority.
UKIP came second, pushing the Conservatives into third place.
Labour's Christopher Hammond was declared the winner in the council chamber at the Civic Centre at 12.17am.
The election was called after the resignation of former city council leader Richard Williams in April.
He stood down after a report found he had misled the public about the resignation of a colleague.
But despite that controversy Mr Hammond was voted as the city council's newest representative, gathering 864 votes in the process.
UKIP's John Sharp came second with 731 votes while the Conservative's Alex Houghton got 704 votes.
Trade Union and Socialist Coalition candidate Sue Atkins got 136 votes, the Liberal Democrats' Adrian Ford 120 votes and the Green Party's Chris Bluemel 107 votes.
