STEPHEN Nolan is to be replaced by Adrian Chiles on BBC Radio 5 Live's late-night show Question Time Extra Time.
The phone-in programme, a spin-off of BBC One's political panel discussion Question Time, began in 2013 with Nolan at the helm.
He will continue to present on Radio 5 Live on Friday to Sunday nights, and is also working with the station on a new "podcast or politics project".
The changes are part of a shake-up to the presenting schedule that is set to come into effect in early January.
In an email to staff, BBC Radio 5 Live controller Jonathan Wall said Question Time Extra Time would be "improving the multi-platform offer of that show to capitalise further on the younger audience who watch the TV show".
He added: "I'm also delighted that Stephen Nolan will continue to host Friday to Sunday nights, even though he has a lot of work commitments in Belfast on TV and radio.
"We are also working with Stephen to come up with either another politics vehicle or a new podcast so that we can make further impact with him to target the 30 to 45 audience."
Nolan (44) presents BBC Radio Ulster's weekday morning phone-in programme The Nolan Show, as well as several programmes for BBC One Northern Ireland including Nolan Live.
In July, it was revealed that he is among the highest-paid presenters on the BBC, receiving an annual salary of between £400,000 and £449,999.
Details of earnings through programmes commissioned for the BBC from his independent production company were not included in the figure.
