David Cameron, Gordon Brown, Ed Miliband And George Osborne Due At Leveson

David Cameron, Ed Miliband, Nick Clegg and George Osborne will all give evidence to the Leveson inquiry into press ethics next week, it has been announced.

The prime minister is due to be grilled over his relationship with the media, particularly his links to News Corporation and his friendship with Rebekah Brooks when he gives evidence on Thursday.

Cameron is also likely to be questioned over his decision to hand Jeremy Hunt responsibility for impartially adjudicating News Corp's bid for BSkyB, despite knowing the culture secretary was strongly in favour of it being approved.

He is likely to be questioned as to the wisdom of hiring former News of the World editor Andy Coulson to be his communications director.

The prime minister will also have to face embarrassing questions about the revelation that he rode Rebekah Brook's horse and the friendly way he spoke to her via text message.
