O'Leary presents a live music show on BBC Radio 2
X Factor host Dermot O'Leary is to host a special Question Time in a bid to engage young people with politics, ahead of this year's general election.
O'Leary will host First Time Voters' Question Time on BBC Three, to be broadcast on 3 March.
The audience of first-time voters will question a panel of representatives from "the main political parties".
The programme is part of a package of BBC Three shows aimed at bringing politics to 16 to 34-year-olds.
The names of the politicians taking part in the special edition of Question Time - which is normally fronted on BBC One by David Dimbleby - will be finalised nearer the time.
O'Leary, best known from fronting TV talent show X Factor, Big Brother's Little Brother and his show on BBC Radio 2, revealed last month he had been in discussions with the the corporation to present a political programme in the run up to the general election.
Although a date for the election has yet to be announced, it is being tipped for May.
Danny Cohen, controller of BBC Three, said: "BBC Three has a unique role to play as the only youth-targeted British television channel with a regular and passionate commitment to current affairs.
"We have exciting plans to cover the build-up to the general election, and are keen to engage young people who may not typically watch political coverage.
"We're delighted to have Dermot O'Leary as our host for this programme. He is passionate about politics and hugely popular with young people."
