British Prime Minister Theresa May said Wednesday she wanted a "mandate to complete Brexit", as MPs looked set to approve her bombshell call for a snap general election in June.
In fiery exchanges in the House of Commons, May repeated that the vote would strengthen her hand against domestic critics seeking to "frustrate the process" of leaving the EU, which formally began last month.
May stunned the country on Tuesday when she announced plans to call a snap election on June 8, despite having repeatedly said she would wait until the next vote scheduled in 2020.
She is seeking to increase her slim majority of 17 in the 650-seat Commons before the battles begin with the EU over Britain's exit bill and future trade and immigration ties.
May insists an early election would provide "certainty and stability" in the negotiations, which will now start after the vote.
In a sign of the key campaign issues ahead, May traded barbs in the Commons with opposition Labour leader Jeremy Corbyn, whose party is deeply divided and languishing up to 20 points behind the Conservatives.
British elections are fixed in law but the 2020 date can be changed with a two-thirds majority in the Commons, and with Labour's support, the motion put Wednesday for a June vote is expected to pass easily.
All sides are now gearing up for the fourth major election in four years, after last June's shock referendum vote for Brexit, the 2015 general election, and the 2014 Scottish independence vote.
Brexit will dominate the campaign, with May, who took office after David Cameron resigned following the EU vote, seeking public backing for her plan to pull Britain out of Europe's single market.
A European Commission spokesman said the "real political" negotiations on Brexit will start after the election.
The smaller Liberal Democrats, who lost most of their seats in 2015 after entering coalition with the Conservatives, are hoping to capitalise on their strong support for the EU to win new support.
Meanwhile the Scottish National Party, which holds most of the seats in Scotland, is pushing its demands for a second referendum on independence in order to maintain close ties with the EU.
"Make no mistake, if the SNP wins this election in Scotland, and the Tories don't, then Theresa May's attempt to block our mandate to hold another referendum when the time is right, will crumble to dust," SNP leader and Scottish First Minister Nicola Sturgeon said.
Like almost everyone else in Britain, the election announcement caught financial markets off guard, amid concerns of the economic implications of Brexit.
