Legislation for an early general election on December 12 has cleared the Commons after MPs voted in favour by 438 to 20, majority 418.
Boris Johnson received a rapturous reception as he arrived at a meeting of the 1922 Committee after his bid for an early general election cleared the Commons.
Tory MPs cheered and banged the table as he arrived for the meeting in Parliament.
Labour leader Jeremy Corbyn said: “This election is a once-in-a-generation chance to transform our country and take on the vested interests holding people back.
“The choice at this election could not be clearer. A Labour government will be on your side, while Boris Johnson’s Conservatives – who think they’re born to rule – will only look after the privileged few.
“We will now launch the most ambitious and radical campaign for real change that our country has ever seen.
“This is our chance to build a country for the many not the few and fit for the next generation.”
Responding to the vote, leader of the Liberal Democrats Jo Swinson said: “This general election will decide the future of our country for generations. It is our best chance to elect a Government to stop Brexit.
“The Liberal Democrats are the strongest party of Remain and will be standing on a manifesto to stop Brexit by revoking Article 50.
“This country deserves better than Boris Johnson and Jeremy Corbyn, and I am excited to take our positive, pro-European, liberal vision to the country as the Liberal Democrat candidate for prime minister.”
