LONDON, United Kingdom (AFP)— Britain’s ruling Conservative Party lost two parliamentary seats to the Labour opposition on Friday, another setback for Prime Minister Rishi Sunak ahead of a general election expected next year.

In both by-elections, Labour overturned huge majorities to further fuel hopes of a return to power after nearly 14 years in opposition.

These losses were just the latest in a string of traditionally safe Tory seats captured by rival parties in recent years.

Labour had played down its prospects in the Conservatives’ previously “super safe” seats of Tamworth and Mid Bedfordshire in England. They became vacant after their MPs quit, one stepping down following sexual misconduct allegations.

But Britain’s ailing economy, the worst cost-of-living crisis in decades and several years of tumult within the Tories, who had three leaders within three months last year, contributed to these latest results.

In Mid Bedfordshire, a Conservative-held seat for almost a century, Labour overturned a majority of nearly 25,000 — the biggest by-election swing since 1945.

Labour leader Keir Starmer hailed the wins as “a piece of history” showing his party had “changed”, after it registered its worst election performance in decades in 2019 under then leader Jeremy Corbyn.

“People are fed up to the back teeth,” he said in Tamworth, having earlier visited Mid Bedfordshire.

Labour represented “a fresh start” after “13 years of decline under this government”, he said.

Polling expert John Curtice said the results were “extremely bad news” for the Conservatives and suggested they will lose the next general election. They currently hold a large overall majority in parliament.

“Unless the Conservatives can fairly dramatically and fairly radically turn things around, then they are in truth staring defeat in the face,” he added.

Sunak called the results “disappointing” but said “mid-term elections are always difficult for incumbent governments.”

Conservative Party chair Greg Hands sought to downplay the results, arguing Tory voters had simply stayed at home, while stressing there were “legacy issues” related to both seats’ former MPs.

“I don’t see any enthusiasm for Labour,” he told Times Radio.

Sunak has recently made several high-profile policy shifts, including cancelling part of a costly high-speed rail link and delaying measures aimed at helping the UK achieve net-zero emissions by 2050.

He argued the moves showed he was a leader willing to take tough decisions in the long term, although critics say they were aimed more at drawing dividing lines with Labour.

After a year in charge, he is struggling to revive his beleaguered party’s fortunes.

The Tories have already seen a 20,000 majority overturned by Labour in a July by-election, while the Liberal Democrats have snatched several of their seats since 2019.

Labour has been leading national polls by double-digit margins for more than a year.

The Tamworth poll was triggered when Chris Pincher quit after being found to have groped two men in an “egregious case of sexual misconduct”.

Then-prime minister Boris Johnson’s handling of the case led to a raft of ministerial resignations that brought the end of his premiership.

The Mid Bedfordshire poll was called when former culture secretary Nadine Dorries, a Johnson loyalist who blames Sunak for his political downfall, quit her seat.

Sunak succeeded Liz Truss as prime minister a year ago after her short-lived tenure rocked financial markets.

He has struggled to win the support of former Johnson allies and others within his party, as well as the wider electorate.

Labour candidate Alistair Strathern won Mid Bedfordshire by 1,192 votes. The 44-percent turnout was seen as resilient for a by-election, which can see as few as 20 percent of the electorate vote.

He said it proved that “nowhere is off-limits for this Labour Party”.

Sarah Edwards, who won Tamworth by a majority of 1,316, said voters had sent a message that “they have had enough of this failed government that has crashed the economy and destroyed public services”.
