Addressing a rowdy parliament, she said moving the election would avoid a clash of priorities in the most sensitive final stages of the two-year talks, ignoring criticism from opposition politicians that she was opportunistic and untrustworthy.
May called the national election in a surprise move on Tuesday, saying it was necessary to boost her majority and provide stability as Britain gears up for two years of negotiations with the European Union about its departure from the bloc.
May has told the House of Commons that holding a vote in June, rather than as scheduled in 2020, will give the country "certainty and stability" as it negotiates its departure from the European Union.
May is seeking to capitalise on her strong opinion poll ratings to increase her slim majority of 17 in the 650-seat House of Commons ahead of tough Brexit negotiations.
"Instead of the country's wealth being hidden in tax havens, we will put it in the hand of the people", he said.
Local Labour Member of the European Parliament Alex Mayer, however, has welcomed the announcement of an early general election as the flawless opportunity to take the fight to the Conservatives. On the streets of the capital, there are signs of voter fatigue.
"The prime minister's attempt to dodge scrutiny shows how she holds the public in contempt", he said. Polls give the Conservatives a double-digit lead over Labour, and May is gambling that an election will deliver her a personal mandate from voters and produce a bigger Conservative majority.
Brexit has divided both of Britain's main political parties, but Labour is also struggling under Corbyn's leadership, with 172 of his 229 MPs past year trying unsuccessfully to oust him.
Sanctuary cities threatened with loss of federal grant money
The department sent the city a letter warning it to comply with federal immigration enforcement of risk losing grant money. Cook County, Illinois, also received a warning, even though it did not get money from the Justice Department a year ago .

Government spokeswoman Ulrike Demmer said Chancellor Angela Merkel spoke by phone Tuesday with British Prime Minister Theresa May.
"We face an unfettered out-of-control Conservative government".
Following considerable wrangling over formats, the 2015 election campaign saw one debate featuring Mr Cameron and Mr Clegg alongside Labour's Ed Miliband and leaders of Ukip, the Scottish National Party, Greens and Plaid Cymru, as well as a second debate with the five non-coalition parties and programmes in which Mr Cameron, Mr Clegg and Mr Miliband answered questions but did not debate face-to-face.
Theresa May is using "bogus" arguments about Brexit to justify an early election motivated by party-political calculation, Liberal Democrat leader Tim Farron has claimed.
Under his leadership, Labour was not part of the "cosy club" at Westminster which thinks it is natural for Britain to be "governed by a ruling elite, the City and the tax-dodgers", he said.
The Tories know there is no chance of Jeremy Corbyn becoming Prime Minister, so they're having an election now before they have to work out even the most basic details of what the Brexit deal will be.
