LONDON — For months, there has been little doubt that the British electorate is disgusted, disillusioned and furious with the political dysfunction and the chaos of Brexit. But there hadn’t been an outlet for the public to vent that anger — until now.

Across much of England, election results for around 8,400 local seats, tabulated on Friday, delivered a vicious backlash against the country’s two main political parties, the governing Conservatives and the Labour opposition. The Conservatives lost more than 1,300 seats, while Labour lost around 80.

“What the voters have been saying is, ‘A plague on both your houses,’” Britain’s leading polling expert, John Curtice, a professor of politics at the University of Strathclyde, told the BBC.

It was a furious electoral tidal wave with unlikely winners: The centrist Liberal Democrats, Greens and Independents picked up hundreds of seats, even as they are marginalized in Parliament. Still, the local results seem unlikely to immediately alter the paralyzed state of Brexit, although that will be tested next week when talks resume between the Conservatives and Labour to try to find a compromise.
