Here is all you need to know about the historic programme.
Why are Prime Minister Theresa May and Labour leader Jeremy Corbyn having the debate?
The PM used an interview in The Sun to lay down the gauntlet to the Labour leader as she battled to win support for her Brexit deal which will see MPs vote on in December 11.
Both party leaders have welcomed the idea of going against one another in Parliament with open arms it seems.
According to Sky News, Jeremy Corbyn said that he would "relish" a head-to-head clash with the PM.
She sparked the challenge when she said that the primetime Sunday night debate would "get the country behind her deal", according to The Daily Telegraph.
If he had declined, she said that she would put herself forward for Q&A style session with a participating audience.
What time is the debate and how can I watch it?
Theresa May has challenged Jeremy Corbyn to a live Brexit TV debate, set for December 9 — the night of the I’m A Celebrity final.
Downing Street has set a provisional date of Sunday, December 9, for the TV debate, just two days before the vote on the deal in the Commons – confirmed as Tuesday, December 11.
It is understood that it will be aired on the BBC although an exact time has not be announced.
What is Labour's position?
Labour's official position is that it would vote against any deal struck by Theresa May with the aim of pushing for a General Election.
Shadow Brexit secretary Keir Starmer claimed Britain could still Remain in the EU".
He told Labour's party conference: "We want a General Election to sweep away this failed government."
After the People's Vote rally in central London, Starmer reaffirmed the party have also not ruled out calling for a second Brexit referendum if they couldn't force an election.
Speaking on BBC's Andrew Marr Show, he said: “If there’s no deal brought back or the deal is voted down, then other options are on the table, one of which is a public vote.
“And in that public vote no options are ruled out, including the option of remain."
On November 25 former PM Tony Blair insisted Jeremy Corbyn is likely to start backing a second EU referendum in the near future.
In the summer of 2016, Britain voted to leave the EU after 17.4 million people backed Leave compared to 16.1 million Remain voters.
