The BBC has confirmed the first stage of a major cost saving programme that will reduce jobs, cut programme output and review parts of its radio and television portfolio.
The corporation says it will deliver around £160m of savings towards a wider target of £500m over the next three years.
Around 550 roles will close across BBC News, Nations and Content by the start of the 2027/28 financial year, with overall headcount expected to fall by between 1,800 and 2,000 positions.
For radio and audio, the BBC plans to reduce output by around 350 to 400 hours across stations and genres by the end of 2027/28, while retaining many of its main daily programmes.
BBC Content is targeting at least £100m in recurring annual savings and will also review its television channels and radio network portfolio as audiences increasingly consume content online.
Several radio programmes are set to close over the next year. On Radio 4, The World Tonight, the Midnight News, Money Box Live, AntiSocial, The Law Show and Crossing Continents will end.
From April, the 10pm slot will carry a domestic news bulletin followed by a simulcast of the BBC World Service programme Newshour.
The BBC World Service will also close The Inquiry, The Conversation and The Fifth Floor by the end of the year.
In News, the broadcaster is seeking savings of around £25m in this first phase, with a net reduction of about 200 roles. Further reductions are expected to be announced in the coming months. BBC News says it aims to save at least £51m by next April.
Other changes include reducing 5 Live Weekend Breakfast to two hours from next April and moving Friday editions of Newsnight to a peak time BBC Two slot from September.
The BBC also plans to combine production teams behind Sunday with Laura Kuenssberg and Newsnight, review senior presenter and editor roles, reduce some linear news gathering positions and make greater use of mobile technology in newsgathering.
Staff have been told voluntary redundancy will be available, although compulsory redundancies remain possible.
