Working-class plumbers surprise candidacy throws spanner into UK Labour leaders election bid

Here is a rewritten version of the news article in a neutral newsroom style:

A working-class plumber has won a seat in the British Parliament, throwing a wrench into Labour Party leader Keir Starmer’s election plans. The candidate, whose identity was not disclosed, defeated a Labour-backed candidate in the Gorton by-election.

The result is seen as a significant upset for the Labour Party, which had been expected to win the seat. The Green Party has claimed victory in the by-election, with its candidate winning 1,046 votes to the Labour candidate’s 934.

The outcome of the by-election has sparked debate about the future of British politics. Sir John Curtice, a leading expert on British politics, has said that the result suggests that the country is more uncertain than ever.

In an editorial, The Guardian has warned that the result could be a “warning shot across Labour’s bows”. Meanwhile, Allegra Stratton, a Bloomberg contributor, has written about how the plumber’s victory could change the UK political landscape.

The by-election was held in Gorton, a constituency in northern England. The result is seen as a significant test of the Labour Party’s strength and popularity ahead of the next general election.
