LONDON - British Prime Minister Rishi Sunak’s governing Conservatives lost two strategically important parliamentary seats on Friday but unexpectedly retained Mr Boris Johnson’s old constituency, in a setback for the main opposition Labour Party.

The by-elections were one of the last electoral tests before a general election expected in 2024 and were seen as an indicator of the two main parties’ prospects, at a time when voters are struggling with high inflation, strikes and rising mortgage rates. Mr Sunak was quick to hail the win as proof the national election was not a “done deal”, telling reporters in a cafe in the constituency: “The message I take away is that we have to double down, stick to our plan and deliver for people.”

But the problems he faces were highlighted by the loss of the formerly safe Conservative parliamentary seat of Selby and Ainsty, where Labour overturned the biggest Conservative majority at a by-election since World War II. 

Labour leader Keir Starmer said the victory showed “just how powerful the demand for change is”.

The Conservatives suffered a crushing loss in another vote, but retained Mr Johnson’s former seat of Uxbridge and South Ruislip by fewer than 500 votes to ensure Mr Sunak avoided becoming the first British leader to lose three by-elections on a single day in more than half a century.

Mr Sunak, a former finance minister and investment banker, has tried to use his technocratic leadership to restore the Conservatives’ credibility after a series of scandals in 2022 forced Mr Johnson to resign, and economic turmoil forced his successor, Ms Liz Truss, to quit after just six weeks.

He is expected to reshuffle his senior ministers soon to pick his team to fight the next general election.

With stubbornly high inflation, economic stagnation, rising taxes and mortgage rates, industrial unrest, and long waiting times to use the state-run health service, the Conservatives had been bracing themselves for the possibility of losing all three contests.

Mr Sunak’s Conservatives are trailing Labour by 20 points in national opinion polls, which suggests the governing party will struggle to win a fifth consecutive general election. 

But Labour’s loss in Uxbridge shows its lead in the polls may not translate into a clear parliamentary majority at the next general election. 

Mr John Curtice, Britain’s best-known pollster, said based on Labour’s performance in Uxbridge, the most likely outcome at the next general election is a hung Parliament. 

“The tide is still a long way out for the Conservatives, and they still have an awful long way to go before they look as though they might have a chance of being able to retain power after the next general election,” he told the BBC. 

The Uxbridge by-election was called after Mr Johnson’s shock decision to quit Parliament in June after he was found to have made misleading statements over parties held in Downing Street during the coronavirus pandemic.

Mr Johnson denied misleading Parliament, but Labour’s failure to take the seat was a surprise. 

The winning Conservative candidate, Mr Steve Tuckwell, said his party’s victory was because of local rather than national factors, pointing to the issue of London’s Labour mayor extending the ultra-low emission zone to include suburban areas such as Uxbridge, meaning some voters had to pay more for their cars.

The other results exposed the Conservatives’ vulnerabilities on two fronts: the loss of the rural Selby seat in the north of England, and one in the south-west, a traditional stronghold.

The Conservatives had won large majorities in both in the 2019 general election.

Labour won Selby and Ainsty in Yorkshire by 4,000 votes, with the Conservatives unable to defend a majority of 20,137.

The seat was vacated after an ally of Mr Johnson resigned in solidarity with the former prime minister.

In Somerton and Frome in south-west England, the centrist Liberal Democrats managed to overturn a Conservative majority of 19,213 after a third MP quit over allegations of sexual harassment and cocaine use.

Mr Curtice said Labour’s loss in Uxbridge shows the “potential fragility” of the party’s lead in the polls, while the Conservatives are vulnerable in southern areas.

The two main “political party leaders have been left with something to think about in the wake of these results”, he said. REUTERS
