The Green Party’s Hannah Spencer has won the Gorton and Denton by-election, with 14,980 votes.
She beat Reform UK’s Matt Goodwin with 10,578 votes, and Labour’s Angeliki Stogia with 9,364 votes.
The constituency had long been considered a safe Labour seat, with the vote triggered by the resignation of former Labour MP Andrew Gwynne in January due to ill health.
He was elected as a Labour MP in 2005 in the previous Denton and Reddish constituency, but was suspended from the party last year after sending offensive WhatsApp messages.
