The BBC Trust begins a service licence review into BBC Radio 5 Live and 5 Live extra today. It comes as the Trust rejects a complaint by the commercial radio station talkSPORT that 5 Live, its main competitor, broadcasts too little news and sport. Whilst it's not been upheld, the BBC Trust says the claim raises "significant and valid questions about what constitutes news on 5 Live", which will now be looked at as part of the review. Anne McElvoy asks Moz Dee, talkSPORT's Programme Director, about the commercial impact the BBC station is having on the network, and Jonathan Wall Deputy Controller of Radio 5 Live 5 explains how it makes sure it meets its public service news remit. This year's Royal Wedding has hardly been out of the headlines as the media gears up to cover one of the biggest events in television history. But how do the logistics of filming the wedding work and how will broadcasters ensure that everything goes smoothly on the day? Anne McElvoy joins APTV's head of operations, Tim Santhouse, in London's Green Park where APTV staff are preparing reporting platforms for the world's media, whilst CNN correspondent Richard Quest joins Anne in the studio to discuss how he's preparing to bring a unique angle to his coverage of the big day. The Independent's sister paper i has announced a new Saturday edition from May. Costing 30p, it'll be 10p more than its week day edition, with sections on leisure and TV.
