Labour has won the Chester by-election – the first public vote since both Boris Johnson and Liz Truss were ousted from Number 10.
Samantha Dixon retained the seat for her party with 17,309 votes – a 61% share and nearly 11,000 more than the Conservative candidate.
Labour was expected to win but the margin was bigger than the last time the seat was contested, in 2019, when the majority was 6,164 – or just under 50% of the votes.
Ms Dixon told Sky News it represented a “resounding mandate” for Labour.
The contest was triggered by the resignation of Labour MP Chris Matheson, who was suspended in October after two allegations of sexual misconduct from a former member of staff were upheld.
The result follows a slump in opinion polls for the Conservatives after a raft of reshuffles in their top ranks.
The party saw a small bounce in their numbers after Rishi Sunak entered Downing Street last month – the third Tory leader this year – but the Tories are still regularly polling behind Sir Keir Starmer’s Labour Party.
This is the first of two by-elections this month, with another taking place on 15 December in Stretford and Urmston, Greater Manchester.
That vote was called after Labour’s former shadow education secretary, Kate Green, announced she was standing down to become the deputy mayor of Manchester, under Andy Burnham.
