Prime Minister Boris Johnson won a resounding election victory on Friday that will allow him to end three years of political paralysis and take Britain out of the European Union within weeks.
The Brexit divorce represents Britain’s biggest political and economic gamble since World War II, cutting the world’s fifth largest economy adrift from the vast trading bloc and testing the integrity of the United Kingdom.
For Johnson, who had faced gridlock in Parliament and focused his campaign on a vow to “Get Brexit Done,” victory was a vindication.
“The people of this country have given us tonight a huge great stonking mandate,” he told activists at Conservative Party headquarters, according to a recording published by Buzzfeed.
“They’ve given us this mandate of course because they want us to do one thing, which you all know, they want us to get Brexit done.”
Nearly half a century after Britain joined the EU, Johnson faces the challenge of striking new international trade deals, preserving London’s position as a top global financial capital and keeping the United Kingdom together.
That last goal was looking more challenging as the election results rolled in, with Scotland voting for a nationalist party that wants an independence referendum, and Irish nationalists performing strongly in Northern Ireland.
In a political earthquake in England, the Conservatives won large numbers of seats in the opposition Labour Party’s so-called Red Wall, traditional working class heartlands once hostile to Johnson’s party.
Brexit, which has shattered old party loyalties and divided Britain along new fault lines, was the cause of the shift. In the Red Wall, a majority of voters favored leaving the European Union and rejected Labour leader Jeremy Corbyn’s ambiguous stance on the issue.
In a symbol of the change, the Conservatives took Sedgefield, once held by former Prime Minister Tony Blair, Labour’s most successful leader.
President Donald Trump was quick to congratulate Johnson.
“Britain and the United States will now be free to strike a massive new Trade Deal after BREXIT. This deal has the potential to be far bigger and more lucrative than any deal that could be made with the E.U.,” Trump wrote on Twitter “Celebrate Boris!”
Educated at the country’s most elite school and known for his bombastic rhetoric, the 55-year-old Johnson should now be able to lead Britain out of the EU by Jan. 31, the current deadline, but will face the complex task of negotiating his country’s future relationship with the bloc.
A divisive figure seen by many opponents as a populist charlatan who played fast and loose with the facts and made unrealistic promises, Johnson may struggle to reunite a divided nation.
But his party’s landslide win marks the ultimate failure of opponents of Brexit, who tried to thwart the 2016 referendum vote through complex legislative maneuvers and could not convert huge anti-Brexit street protests into a coherent political strategy.
With results in from almost all 650 parliamentary seats, the Conservatives had won 361, their biggest election win since Margaret Thatcher’s 1987 triumph.
Labour, led since 2015 by the veteran socialist Corbyn, had won just 203 seats, the party’s worst result since 1935.
Corbyn’s offer of a radical agenda failed to win over voters, while his equivocal position on Brexit left many angry and confused, especially in Red Wall areas where large majorities had voted for Brexit in 2016.
Corbyn said he would quit as Labour leader after a period of reflection.
Sterling soared, on course for one of its biggest one-day gains in the past two decades. The pound hit a 19-month high versus the dollar and its strongest levels against the euro since shortly after the 2016 Brexit referendum.
After Jan. 31, Britain will enter a transition period during which it will negotiate a new relationship with the EU.
This can run until the end of December 2022 under current rules, but the Conservatives have pledged not to extend the transition beyond the end of 2020.
