According to The Times, the nine Cabinet Contender debates will see Labour ministers, their Shadow rivals and Liberal Democrat counterparts discussing the key issues ahead of the general election.
The programmes will run in addition to the BBC's main debate between Labour Prime Minister Gordon Brown, Conservative leader David Cameron and Liberal Democrat leader Nick Clegg.
The Daily Politics host Andrew Neil will front the Cabinet Contender debates on BBC Two in the two weeks before the election date, which is still to be confirmed. Sky and ITV will also host their own leader's debates, but neither broadcaster has revealed similar plans to support Cabinet-level programmes.
The ministers, including Lord Mandelson, David Miliband, Vince Cable and Ken Clarke, will appear on BBC Two to discuss subjects such as health, education, defence and crime.
Nearly all participants have signed up to take part in the debates, although Labour would not reveal whether chancellor Alistair Darling will contribute to the economy discussion, despite his Tory shadow George Osborne already agreeing to appear.
A final debate will carry the theme of "trust in politics" and air the day before the election, although no participants have been confirmed as yet for that discussion.
Each programme will be broadcast from 2.15pm to 3pm on The Daily Politics show, but not in front of a live studio audience as with the main election debates.
Despite the party leaders having to adhere to a strict code of conduct, the Cabinet Contender debates will be more relaxed.
All three ministers will get 45 seconds to deliver their opening statements before facing questions from Neil and a BBC specialist reporter. Viewers will also get the opportunity to submit questions via email.
The format will be expanded to a four-party system for debates on the environment and immigration, with the Green Party and UK Independence Party taking part. Additional debates will be held in Scotland, Northern Ireland and Wales for key issues, such as health and education.
The Daily Politics editor Robbie Gibb said: "We are now in the very final stages of negotiating these Cabinet-level debates.
"It's clear that the public has a huge appetite for live head-to-head debates of this nature and they will provide a unique opportunity for the public to compare and contrast what each party has to offer on the issues that matter most to the public like crime, health, schools and economy."
