Yesterday, the BBC director general, Tony Hall, announced what he called "the greatest commitment to arts for a generation" with the launch of BBC Arts. What is the future of arts on TV and what can BBC Arts learn from Sky Arts? Joining Steve will be Sir Peter Bazalgette, chair of Arts Council England, Gillian Reynolds of The Telegraph and the BBC's new director of arts, Jonty Claypole.

Turkey's prime minister Erdogan has carried out his threat to ban Twitter in his country, but what impact has this had and how are journalists getting round this? Political columnist Yavuz Baydar joins Steve from Istanbul.

And, as Al Jazeera journalist Peter Greste spends another week in jail in Egypt awaiting trial, what are the prospects for his freedom - and can his colleagues Mohamed Fahmy and Baher Mohamed hope to be freed at the same time? Former C4 reporter Sue Turton, now of Al Jazeera, has also been charged, albeit in her absence and she brings Steve up to date.
