Brexit wrought more havoc on Britain's main political parties in European Parliament elections, with both Conservatives and Labour scoring their worst results in decades as voters opted for politicians with clear pro- and anti-European Union messages.

With nearly all the vote counts complete, Nigel Farage's Brexit Party, which wants the U.K. to leave the EU without a deal, was in first place, with 32 percent of the vote. In second place, with 20 percent, were the Liberal Democrats, who want to stay in the bloc. Labour, which is split about what to do, was third with 14 percent. The anti-Brexit Greens had 12 percent.

In fifth place were Theresa May's Conservatives at 9 percent, a catastrophic result for the party of government. The heavy defeat immediately sparked calls for the Tories speed up efforts to leave the bloc or risk being destroyed at the next general election.
