Many of Labour's traditional working-class supporters voted to leave the EU, particularly in areas that have experienced a large influx of eastern European immigrants in recent years.
The Labour party has seen a significant decline in polls since the last general election, as it struggles with infighting over its leader Jeremy Corbyn, and its unclear position on Brexit.
Speaking during Prime Minister's Questions, he said: "Over the last seven years, the Tories have broken every promise on living standards, the deficit, debt, the National Health Service and schools funding".
"We won't be doing television debates", she said on Wednesday.
The general election, which will be held on June 8, is predicted to favour May's Conservative Party, with good popularity evident in recent opinion polls. However, the figures appear to contradict her statement: some three quarters of MPs and two thirds of the Lords voted for Article 50.
Bale said a bigger majority would give May a new batch of loyal Conservative lawmakers and leave her less at the mercy of euroskeptics in her party "who otherwise could have made negotiations much more hard".
The UK currency's strength weighed on the FTSE 100 which was down 0.1%, suffering further after more than £45 billion was wiped off the index just a day earlier.
The Commission spokesman said "real political negotiations" on Brexit would not start until after the vote.
She said the country now has a "unity of purpose" and a desire for the government to "get on" with implementing Brexit and "making a success of it".
"It's about providing the strong and stable leadership this country needs to take Britain through Brexit and beyond, it's about strengthening our hand in the negotiations that lie ahead, and it's about sticking to our plan for a stronger Britain that will enable us to secure that more stable and secure future for this country and take the right long-term decisions for the future".
She "signalled that she will put Brexit at the heart of the election debate", says The Times, saying she was acting now because Labour and the Liberal Democrats opposed the government's plans for leaving the EU. "The country is coming together but Westminster is not", said May. Our opponents believe because the government's majority is so small that our resolve will weaken and that they can force us to change.
Mrs May also told The Sun newspaper of her concern that the May 2020 election date laid down by the Fixed-Term Parliaments Act would leave her open to pressure from Brussels as the two-year withdrawal negotiations drew to a close in March 2019.
If the election is approved Wednesday, Parliament will be dissolved on May 2, sparking nearly six weeks of campaigning. Labour and the Conservatives, the two largest parties, have both said they would enact the European Union referendum result.
Although Labour has backed the snap election, Corbyn asked how the United Kingdom public is expected to trust May.
A number of MPs abstained from Wednesday's vote, including those with the Scottish National Party.
Scotland's First Minister also told Sky News she was open to a "progressive alliance" with Labour and the Liberal Democrats to keep the Tories out if the "parliamentary arithmetic" added up.
