The leader of the Liberal Democrats has said the party’s historic win in the Chesham and Amersham by-election will “send a shockwave through British politics”.
Sir Ed Davey claimed that the result demonstrates that the “Blue Wall” of Tory southern seats could be vulnerable after Boris Johnson’s Conservative Party suffered a humiliating defeat in the contest.
Liberal Democrat Sarah Green is the country’s newest MP after winning the Buckinghamshire seat, which had been a Conservative stronghold since its creation in 1974.
The Tories sought to limit the damage, insisting it was difficult for governing parties to win by-elections, but defeated candidate Peter Fleet acknowledged the Conservatives had to rebuild “trust and understanding” with voters.
The by-election was triggered by the death of former Cabinet minister Dame Cheryl Gillan, who took the seat with a majority of 16,233 in the 2019 general election – some 55 per cent of the vote.
In a stunning result, Green took 56.7 per cent of the vote to secure a majority of 8,028 over the second-placed Tories.
Sir Ed told BBC Breakfast on Friday: “I think this will send a shockwave through British politics.
“Liberal Democrats have had good wins in the past but this is our best ever by-election victory and it if was repeated across the South, literally dozens of Conservative seats would fall to the Liberal Democrats.
“People talked about the Red Wall in the North, but forgotten about the Blue Wall in the South, and that’s going to come tumbling down if this result is mimicked across this country.”
The Green Party came third with 1,480 votes, with Labour trailing in fourth with just 622 votes, losing the party’s deposit in the process.
Polling expert Sir John Curtice told BBC Radio 4’s Today programme that he made it the “worst Labour performance in any by-election” after it took just 1.6 per cent of the vote.
The inquest has already begun – on both sides of the aisle. Theresa May’s former chief of staff, Gavin Barwell, suggested that the result is a “mirror image” of last month’s Hartlepool by-election.
Figures on the Labour left suggested that the Lib Dems’ victory rubbished Sir Keir Starmer’s claims that a ‘vaccine bounce’ is responsible for the party’s struggles in the polls.
Others suggested that it paved the way for inevitable arguments about the viability of a so-called ‘progressive alliance’ before the next general election.
Dominic Cummings, meanwhile, decided that the result shed a bit of light on the “ephemeral emotional waves of the lobby’s constant hysteria”.
Meanwhile those with ties north of the border were simply keen to see the result as a portent of further upsets to come.
