The candidates to be Conservative Party leader – and the UK’s next prime minister – are to take part in a live televised debate on BBC One later.
The programme at 20:00 BST hosted by Newsnight presenter Emily Maitlis will be broadcast two hours after Tory MPs vote in the second bout of the contest.
Questions will be from the public but there will not be an audience, opening or closing statements.
The front-runner in the contest, Boris Johnson, says he will be taking part.
The former foreign secretary missed Sunday’s TV debate on Channel 4.
Environment Secretary Michael Gove, Foreign Secretary Jeremy Hunt, Home Secretary Sajid Javid, ex-Brexit Secretary Dominic Raab and International Development Secretary Rory Stewart are the other leadership hopefuls.
Conservative MPs have voted by secret ballot in the Commons in the next stage of the leadership contest, with a result expected some time after 18:00 BST.
Candidates will be eliminated from the contest – and therefore will not be part of the TV debate at New Broadcasting House in central London – if they come last or fail to secure at least 33 votes.
The hour-long programme, called Our Next Prime Minister, will see the candidates face questions from viewers via video links from BBC studios across the UK.
The BBC received thousands of questions ahead of the debate, with the largest number being about Brexit.
Other topics submitted included HS2, public spending and climate.
Each candidate will be given an opportunity to answer every question posed.
The programme team will select the questions to be asked after making an editorial decision on the ones that best represent the issues likely to face the next prime minister.
The BBC said the questions will come from a cross-section of society, not necessarily all Conservative voters.

What type of questions have BBC viewers been asking?

Question topic: The other candidates
Hopes for the debate: “I like to hear, what I think are, truthful answers rather than whimsical, evasive or answers that politicians think the public want to hear”
