The plans include putting popular radio shows on TV, starting with the BBC Radio 5 Live Nicky Campbell programme

The BBC has said it is investing in "new capability to cover breaking news stories" for a TV news channel which is expected to launch in April 2023.

The channel, which will be called BBC News, is replacing the corporation's two existing, separate UK and global news channels.

It is part of plans for a "digital-led, streamlined organisation".

About 70 UK-based BBC staff will lose their jobs as a result of the merger, it is understood.

But in Washington DC, about 20 jobs will be created.

BBC News digital director Naja Nielsen said the way people consume current affairs is changing.

"In recent years we've seen a huge surge in audiences coming to our live coverage, with tens of millions following live pages when big stories and events unfold," she said.

"As the world's most trusted source of news, with a huge depth and breadth of expertise, the BBC is uniquely placed to offer audiences the best analysis and explanation as these stories are unfolding."

She said investing in this would mean "our news channel and digital teams will work hand-in-hand to bring the best journalism to audiences both at home and abroad".

A new feature will be the BBC investing in "visualising" programmes based on popular radio shows, starting with the BBC Radio 5 Live Nicky Campbell programme, which will be broadcast on BBC Two on weekday mornings, as well as on the UK stream of the new channel.

The move is part of cost-saving measures - in January, Culture Secretary Nadine Dorries confirmed the BBC licence fee is to be frozen at £159 for two years.

In May, the corporation announced that as well as merging its two news channels, it would stop airing CBBC and BBC Four as traditional broadcast channels. It also said it would axe its regional TV news programmes in Oxford and Cambridge.
