MPs have backed Prime Minister Theresa May's call for an early General Election with an overwhelming 522 votes to 13.
The Fixed-Term Parliament act required a two-thirds majority in the House of Commons, meaning 434 votes with the SNP abstaining.
Wednesday's margin of 509 by far exceeded that target. The election is scheduled to go ahead on 8 June - in just 50 days' time.
The vote came after May called for a snap election on Tuesday afternoon, claiming Britain needed political stability ahead of the Brexit negotiations.
Sterling surged to a six-month high on Tuesday following the Prime Minister's speech, while the FTSE 100 suffered its worst daily fall since the Brexit vote.
Industry players have already warned a new government could spell further disruption to pension policy. But advisers shrugged off any such worries, suggesting Brexit negotiations would form the new government's priority instead.
Meanwhile, ex-chancellor George Osborne announced on Wednesday he would not stand for re-election on 8 June, saying he is leaving Westminster "for now". The MP for Tatton has recently taken on an advisory role at Blackrock and the editorship of the London Evening Standard newspaper.
So far the Conservatives seem to have the upper hand in the polls, with pollsters suggesting a lead of about 20 points over the Labour opposition.
