What is the format of the debate?

Johnson v Corbyn will take part in front of a live studio audience of about 200 people.

As part of format agreed with parties and ITV, both Jeremy Corbyn and Boris Johnson will stand behind podiums, Corbyn will be positioned on the left side of the screen and Johnson on the right. They will each have one minute each for their opening statements and 45 seconds for their closing statements, with Corbyn speaking first in both cases after lots were drawn. 

Questions asked of the leaders following their opening statements will be selected from ITV viewers. 

Where is the debate and who is leading in polls?

The debate is to be held by ITV at MediaCity in Salford. The Labour leader will be hoping he can give Boris Johnson a bloody nose, with Labour currently trailing in the opinion polls, Mr Corbyn goes into the event hoping for an opportunity to make up ground on the Conservatives. The Prime Minister, who was criticised for his reluctance to debate directly with his rivals in the Tory leadership election, will be seeking to avoid any misstep which hands ammunition to his opponents.

As well as the ITV debate, there will be a number of other televised political battles. Sky is set to host a three-way debate including Mr Johnson, Mr Corbyn and Lib Dem leader Jo Swinson on November 28.

The next day, the BBC will host a seven-way debate in Cardiff on November 29, between leaders or senior figures from the seven major GB political parties.

ITV will be broadcasting a seven-way election debate on Sunday 1 December.

What are the key topics?

While the questions and the talking points are not yet known, it is a safe bet to state that Brexit will be on the agenda. However, the NHS, the economy and even defence and broadband could all be on the agenda. The character and personal issues of the two leaders may also be brought under scrutiny.
