LONDON — Prime Minister Boris Johnson’s Conservative Party on Friday lost control of a parliamentary seat they have dominated for nearly 200 years, in a shock election result seen as a voter backlash against a British leader beset by crises and scandal.

The centrist Liberal Democrats won the North Shropshire seat by nearly 6,000 votes, overturning a 23,000 vote Conservative majority from 2019 with a huge swing.

The defeat was described as ‘a kicking’ for the Conservatives. It will ratchet up the pressure on Johnson from his lawmakers, who are in mutinous mood as they fear the party’s reputation and electoral prospects are now suffering under Johnson’s leadership.

“Tonight, the people of North Shropshire have spoken on behalf of the British people. They have said loudly and clearly: ‘Boris Johnson, the party is over’,” Liberal Democrat candidate Helen Morgan said in her victory speech.

“Our country is crying out for leadership. Mr Johnson, you’re no leader.”

The shock result comes at a time when Johnson is facing criticism on several fronts, including over reports his staff held parties last Christmas when the country was in lockdown.

Nationwide opinion polls show his ruling Conservatives falling behind their main rivals, the Labour Party.

“Voters in North Shropshire were fed up and they gave us a kicking and I think they wanted to send us a message,” Conservative chairman and lawmaker Oliver Dowden told Sky News, which is owned by NBC News’ parent company, Comcast. “I want to say as chairman of the Conservative Party, we’ve heard that loud and clear.”

Doubts about Johnson’s leadership have been stoked further by public outcry over lawmakers’ second jobs, criticism of the way Johnson funded the lavish refurbishment of his flat, and a surge in Covid-19 cases.

The vote for the North Shropshire area, one of 650 seats in Britain’s parliament, was called outside of the regular election cycle because the incumbent Conservative resigned after he was found to have broken rules on paid lobbying.

The government attempted to prevent that resignation by changing rules designed to stop corruption in parliament, but was forced to backtrack after the move provoked an outcry about integrity and trust under Johnson’s leadership.

The Conservatives had won every previous election for the mostly rural area of central England since the constituency was created in its current form in 1983.

So-called by-elections are often used by voters to punish the ruling party, but the scale of the Liberal Democrat victory will be taken as evidence of deep public dissatisfaction.

Johnson still maintains a large majority of the seats in parliament after a comprehensive 2019 election win built on a promise to ‘Get Brexit Done’ that united traditional right-leaning Conservative voters with a swathes of new supporters.

North Shropshire was a pro-Brexit, staunchly Conservative area. Analysts say Friday’s heavy defeat may further undermine Johnson’s authority over lawmakers already in open revolt over plans to introduce Covid-19 passports.

Britain’s next nationwide election is due in 2024.
