5 Live's Barnett joins Newsnight
BBC Radio 5 Live presenter Emma Barnett has been named as one of the hosts of a new-look Newsnight.
Emily Maitlis will become the new lead presenter of the BBC Two current affairs programme following Evan Davis's departure.
Kirsty Wark will have an "enhanced" role on the programme, while Barnett joins as a new presenter. She will continue to present her daily morning show on 5 Live.
"I can't wait to get started at Newsnight at a time when no one can predict the next hour in British politics, never mind the next evening," Barnett said.
Davis left the programme last year to take over from Eddie Mair as the lead presenter of PM on BBC Radio 4.
Maitlis said she was "delighted to be moving into this role at a time when Newsnight feels so pivotal to our understanding of this extraordinary moment in British history".
This is the first time the programme has had an all-female presenting team and follows the appointment of Fiona Bruce as David Dimbleby's successor on Question Time.
Newsnight editor Esmé Wren said: "This is a tremendous presenter line-up that sends out a clear signal about the programme's growing ambition.
"All three presenters bring substantial political clout and a wealth of expertise across a broad range of subjects."
