This is the best summary I could come up with:

Damien Egan, who resigned as the mayor of Lewisham in south-east London to contest the seat even though it is being abolished at the next general election, is celebrating victory after a professional and energetic Labour campaign.

It will be a blow for Rishi Sunak’s hopes of clinging on to power at the next general election, and even before the result came in the prime minister was criticised for presiding over an insipid effort to defend Kingswood.

The byelection was called after Chris Skidmore, a leading Tory voice on green issues, resigned in protest against the government’s dash for oil and gas.

Labour poured MPs and activists into the area behind him, seeing it as a way of maintaining the impetus of its push for Downing Street and as an important test of its hopes of challenging the Tories and the Liberal Democrats in south-west England.

Bromiley previously said his experience as a youth worker would help him tackle crime among young people, promised to stop the Labour-led local council from “hacking into the greenbelt” and said he would work to regenerate the high street.

John Curtice, professor of practice, politics, at Strathclyde University, told the BBC: “Clearly a bad result for the Conservatives, but it’s not quite the big success for Labour on quite the scale that perhaps Sir Keir is trying to claim.”
