What's the head-to-head format?
Each leader will have one minute for their opening statement - with Corbyn set to go first after lots were drawn - and 45 seconds for closing statements - with Johnson set to close.
The debate will last one hour in front of the studio audience of around 200 people.
Questions will come from ITV viewers and will broadly reflect a range of society, from different political backgrounds.
Questions are from ITV viewers responding to a call for questions on news bulletins throughout the UK and online.
The ITV Election Interviews
There will be a special one-hour live interview programme at 10pm offering party leaders the chance to set out their own electoral offer and make observations on what has been said in the debate.
Jo Swinson of the Liberal Democrats, Nicola Sturgeon of the SNP, Nigel Farage of The Brexit Party and Sian Berry co-leader of the Green Party will be interviewed individually in consecutive face-to-face interviews with Nina Hossain, from a studio in East London.
