Andy Burnham, the mayor of Greater Manchester in northern England, won a seat in Parliament on Thursday, a pivotal step in his plans to challenge Prime Minister Keir Starmer for leadership of the Labour Party and the country.
Mr. Burnham easily defeated a field of candidates from more than a half-dozen parties, winning 24,937 votes — a resounding majority of about 55 percent.
In brief remarks after his victory was declared in the early hours of Friday morning, Mr. Burnham said his win was “a loud cry for change” from the people of Britain. It is a message he intends to take to his bid to become prime minister.
“I do say to my own party, this is a final chance to change,” a beaming Mr. Burnham said. “We must hear it, we must act upon it, and we must get it right. There will be no second chance, but it is a chance now from this result tonight to build a new politics based on unity and hope.”
Reform U.K., the populist right-wing party led by Nigel Farage, failed to secure the seat, in spite of its success in a set of local elections last month. Rob Kenyon, the Reform candidate, did better than his party did in the general election two years ago but came in second with 15,696 votes, or about 34 percent of the ballots cast.
Election officials announced the results of the special election in Makerfield, an area made up of former coal mining villages and market towns, early on Friday morning.
The win will galvanize supporters of Mr. Burnham, who have argued that he offers Labour its best chance of challenging Reform. In his remarks, Mr. Burnham alluded to the desire to oppose the rise of populist right-wing politics.
He said his victory was a chance for the country to turn “away from the path that takes us to a divided, dark politics of the kind we see in the United States.”
Mr. Kenyon was partly undercut by the presence of a candidate representing Restore Britain, a far-right party that argues that Mr. Farage and his followers are not extreme enough. The Restore candidate won 3,111 votes, or almost 7 percent of the ballots.
But added together, the vote for the two right-wing parties would have still fallen far short of the number needed to defeat Mr. Burnham and win the race.
Mr. Burnham may now begin the process of trying to oust Mr. Starmer, who has become one of the least popular prime ministers in modern British history.
When Mr. Burnham might challenge the prime minister — and how Mr. Starmer will respond — remains unclear.
The prime minister has said he will fight to stay in the office he won almost two years ago. But several Labour lawmakers have publicly said Mr. Starmer should step aside, for the good of the party and the country, if Mr. Burnham challenges him.
