Mr Corbyn will claim the future of the National Health Service and English schools are on the line in the election and new analysis shows the impact of the Tories' plans. Occasionally something a politician says or does will be significant enough to rise up in into the general public consciousness, but by and large people's views of party leaders is filtered through the picture that is presented to them in the press and on TV.
"And it couldn't have been more different to Jeremy Corbyn - who flannelled under pressure and couldn't get past 30 years of words and deeds that put him on the wrong side of the British people".
After seeing the Conservative polling lead dwindle to single figures in the wake of the Conservative manifesto and subsequent furore over social care, Mrs May ditched her "strong and stable" mantra and attempted to shift the focus back to Brexit during the Sky and Channel 4 broadcast.
"It is a hypothetical question", he said.
The prime minister ridiculed Corbyn's positions on Brexit as lurching from "half-baked plan to half-baked plan".
Another member of the audience said he could not vote Labour due to Mr Corbyn's "ruthless, short-sighted" policies, which include raising corporation tax to 26%, a £10 an hour minimum wage and imposing VAT on private school fees.
She said budgets were now being protected for both counter-terrorism forces and overall policing.
She added: "But I am prepared - prepared to take the hard decisions that leadership demands".
In an effort to get back to her key election messages of leadership and Brexit, she said Mr Corbyn was not prepared for the crunch talks with Brussels that will start within days of the General Election and would find himself "alone and naked" in the negotiations.
The Labour leader came off the better of the two, giving a more assured performance during the audience question and answer section and looking confident in an awkward interview exchange with veteran broadcaster Jeremy Paxman.
Mr Corbyn was challenged by an audience member who claimed the Labour leader had "openly supported the IRA in the past" by attending a commemoration for eight IRA members killed by the SAS in Loughgall.
"Jeremy Corbyn is saying we can promise you this, we can promise you this, we can promise you this and she is saying no, there's going to be another two million people over 75 in the next 10 years".
He was pressed by Mr Paxman over comments he made following the Argentine invasion of the Falklands that "young unemployed men" were being sent to the South Atlantic to die in pursuit of a "Tory plot".
May and the leader of the main opposition Labour Party are used to facing each other across the floor of the House of Commons for the weekly battle known as Prime Minister's Question time. "I felt that she was exploiting the situation".
