The Labour leader Jeremy Corbyn has challenged the Prime Minister to join him for a live TV debate in Cambridge tonight.
Mr Corbyn will join the leaders of the Liberal Democrats, UKIP, the Green Party and Plaid Cymru.
The SNP is sending their leader at Westminster and the Conservatives are sending Home Secretary Amber Rudd.
However the Prime Minister Theresa May insisted she would not be attending the BBC Election Debate which is expected to attract an audience of millions.
Mr Corbyn said: "I invite her to go to Cambridge and debate her policies, debate their record, debate their plans, debate their proposals and let the public make up their mind."
Mrs May said: "I think debates where the politicians are squabbling amongst themselves doesn't do anything for the process of electioneering.
"I think it's actually about getting out and about, meeting voters and hearing directly from voters."
Green co-leader Caroline Lucas said Mrs May's decision showed "extreme cowardice", while Liberal Democrat leader Tim Farron said she was "clearly terrified of having to defend the cruel and heartless policies in the Conservative manifesto".
