GB News has announced broadcaster Mark Dolan has joined the channel and will present a prime-time programme.
He will front Tonight Live With Mark Dolan on Fridays, Saturdays and Sundays, the channel said, adding he will also appear on other shows.
Dolan, who previously worked for Talkradio, replaces the slot currently occupied by Nana Akua.
She will now present a new programme that will air on Saturdays and Sundays at 3pm.
Dolan said: “My show will tackle the issues that really matter to people across the United Kingdom in a stimulating, informative but entertaining way. My one promise is that it won’t be boring.”
The move comes amid reports of turmoil at the channel, which launched in June promising to offer an alternative to the likes of the BBC and Sky News.
Journalist Guto Harri is said to have quit GB News following a row over him taking the knee during a debate on the racism directed towards England football players.
The channel’s director of news and programmes, John McAndrew, is also said to have stepped down.
GB News chairman Andrew Neil, who has been absent from the channel after announcing a break two weeks into its launch, said it was “finding its feet” but had a “great future” ahead of it.
Nigel Farage has been announced as joining the channel.
