United Kingdom lawmakers overwhelmingly vote to support snap election
May said she had been reluctant to ask parliament to back her move to bring forward the poll from 2020.
May wasted no time, going from the vote in Parliament to kick off her campaign with a speech in to supporters northwestern England.
Today, they voted 522 to 13 in favor of holding the snap elections on June 8.
The next general election wasn't due until 2020, one year after Brexit talks are scheduled to conclude.
"That would be in nobody's interest", May said.
The opposition Labour Party and Liberal Democrats say they welcome the chance to put their policies to voters, though the Scottish National Party says the election call is a cynical ploy.
Blair, who won three general elections as the former leader of Labour Party, said in statement on Wednesday that May wanted to force the final European Union deal upon the people regardless of how good or bad it might be and that she would seek to suppress any opposition through a landslide victory in the upcoming vote.
Despite Corbyn's bravado, his party is demoralized and divided under his left-wing leadership and is expected to fare badly.
Liberal Democrat leader Tim Farron said that broadcasters should hold debates anyway, with an empty chair in May's place.
He said: "I think she had little choice because so many parliamentarians have not accepted the referendum result and are seeking to reduce her ability to secure a good deal for Britain - and really I think in the hope of forcing a change of mind from the British public". The government's current working majority is only 17 seats.
This decision comes despite repeated assurances to the contrary that she would do nothing of the kind.
"It's the right decision, it's in the national interest, and that's what this election is about".
The prime minister, who took office after David Cameron resigned following the European Union vote, is seeking a personal mandate for her plan to pull Britain out of Europe's single market.
"I believe in campaigns where politicians actually get out and about and meet the voters", she said.
Asked if her manifesto would guarantee that in 2020 the United Kingdom would be clear the European Court's jurisdiction and EU free movement, she said only that United Kingdom will be ensuring "we negotiate the best possible deal".
The Conservative Party has recorded its highest level of support since early 2008, according to a poll conducted after Prime Minister Theresa May called for a snap general election on June 8.
May earlier ruled out participating in televised debates with other leaders.
And Plaid Cymru leader Leanne Wood - whose profile received a major boost from her involvement in two of the 2015 broadcasts - said: "Theresa May should be empty chaired if she doesn't show up to any planned TV debates".
Mrs May could also be ready to ditch promises made in David Cameron's 2015 general election manifesto, such as the commitment to spending 0.7% of national income on foreign aid.
Government spokeswoman Ulrike Demmer said Chancellor Angela Merkel spoke by phone Tuesday with British Prime Minister Theresa May.
