Fonejacker star Kayvan Novak is to play a Julian Assange-type figure in a forthcoming BBC4 production. Asylum is described as "a satirical comedy about a government whistle-blower and a millionaire internet entrepreneur trapped together in a London embassy".

The programme is the idea of Novak and his Fonejacker producer Tom Thostrup. It is written by Peter Bowden and Thom Phipps..

Asylum will be broadcast next year as part of a series of programmes marking the 800th anniversary of Magna Carta. The Taking Liberties season also includes a six-part series of Up The Women, written by and starring Jessica Hynes and also starring Rebecca Front (Nighty Night, The Thick Of It). It’s 1910, and having been inspired by the Women’s Suffrage Movement in London, the ‘Banbury Intricate Craft Circle’ have set up their own, hilariously ineffectual, movement, calling themselves ‘The Banbury Intricate Craft Circle Politely Request Women’s Suffrage’.

Rory Bremner will also feature in the same season, with Rory Bremner’s Coalition Derby taking on the coalition. In May 2010, Britain went to the polls to elect a new government. Except they didn’t. Days later, two men got hitched in the Downing Street Garden and promised to govern in the interests of the country. What happened next? Who won? Who lost? Recorded in front of a live audience, Rory Bremner brings some new characters to life, alongside old favourites to make sense of the nonsense and ask, ‘what is going on?’

Taking Liberties will also include a day of debate on the 750th anniversary of England's first parliament, a fly-on-the-wall documentary by Michael Cockerell shot inside the House of Commons, and a series on the struggle to win votes for women, presented by Amanda Vickery. David Starkey and Melvyn Bragg will present documentaries tracing the document's history and Ben Miller stars as King John in a Horrible Histories special.
