Labour said it will vote in favor of a new election, meaning she should be able to get it through.
In a statement focusing on her record locally, she said: "It has been my absolute pleasure to attend countless festivals and celebrations in our local shuls and community centres".
As an unelected, pro-Remain prime minister, she entered 10 Downing Street under an unprecedented cloud of uncertainty.
"And the negotiations with the European Union will reach their most hard stage in the run-up to the next scheduled election". She said a "hard Brexit" must be rejected.
At present, May's governing Conservatives have a small majority, with 330 seats in the 650-seat House of Commons.

Speaking to the BBC's World at One, he said: "This is about getting a mandate from the British people to deliver an outcome".
Theresa May is seeking to hold a General Election on 8 June arguing it is the only way to secure stability ahead of Brexit.
That is highly likely to happen on Wednesday.
Jeremy Corbyn welcomed Theresa May's call on Tuesday for an early general election, describing it as a chance for the British people to vote for a government that works for the majority.
Wyn Grant, politics professor at the University of Warwick, said: "Clearly if Labour suffer a big defeat, Corbyn is going to go".
Professor Christopher Bovis of Hull University Business School, said the election would have little impact on the United Kingdom economy. Every opinion poll points to a historically poor result for Labour, with the party facing the prospect of losing dozens of seats. "And as elections are so unpredictable, there is always the outside risk it could spark a reversal in the entire Brexit process".
The Scottish National Party now holds 54 of Scotland's 59 seats in the British Parliament, making it the third-largest party there.
