The BBC has revealed plans for large cuts to its services, proposing to shut two domestic radio stations and large parts of its website.
The director general of the British public broadcaster, Mark Thompson, said he expected the plans would see an extra Stg 600 million diverted into programme-making.
Broadcasting workers' union Bectu said it feared up to 600 jobs could go.
Union leaders have accused Mr Thompson of offering up BBC services and jobs as a political sacrifice, ahead of the general election due in Britain later this year.
BBC 6 Music and Asian Network are facing closure, and half the websites on BBC online will close by 2013, Mr Thompson announced. The teen services Switch and Blast would also close.
