GB News will attempt to shake up the broadcasting landscape when the news network launches its TV channel in early June.
The news service, spearheaded by veteran broadcaster Andrew Neil, has announced plans to go live on Sunday June 13.
In a tweet, the channel said it would launch at 8pm with a special programme, ‘Welcome to GB News’.
The 24-hour news channel plans to battle the BBC and Sky News by targeting audiences that have become disillusioned with traditional broadcasters’ coverage.
The channel, backed by the American broadcaster Discovery, has hired a raft of seasoned journalists, including veteran ITV news anchor Alastair Stewart and former BBC News presenter Simon McCoy.
In recent days it has been ramping up the publicity around its forthcoming launch, with social media videos of its new London-based studios in Paddington.
GB News will air on channel 236 for Freeview and YouView viewers, station 216 on Freesat, as well as being broadcast across Sky, Virgin Media and through a dedicated on-demand streaming service.
TV platforms had been on alert for GB News to go live as soon as May 31, sources had told The Telegraph.
GB News was locked in a race with Rupert Murdoch to become the first organisation to launch a right-leaning news channel before the summer.
However, News UK scrapped its plans for a TV channel last month, claiming it was not “commercially viable”. It is now focused on launching a news streaming service.
Alongside Discovery, GB News is backed by hedge fund manager Sir Paul Marshall and the Dubai-based investment fund Legatum.
The broadcaster has secured enough investment to hire 120 journalists in its attempt to shake up the media landscape.
The Telegraph’s economics commentator Liam Halligan is also joining GB News as economics and business editor.
Mr Neil will anchor a prime time news and interview programme, while former Apprentice winner Michelle Dewberry will host Dewbs & Co every weeknight.
The Sun newspaper’s former executive editor Dan Wootton will also front Tonight with Dan five nights a week.
