George Osborne facing questions over recruitment of Andy Coulson at Leveson Inquiry As well as overseeing the Treasury, Mr Osborne plays a pivotal role in Downing Street and is intimately involved in many of the decisions taken there. His extensive political role has led to jibes that he is a part-time chancellor. Both the Chancellor and the Prime Minister are also expected to come under pressure over the handling of News Corp's bid to control BSkyB. Rupert Murdoch told the inquiry that they had previously enjoyed a "warm personal relationship." In 2008, Mr Murdoch's wife, Wendi, and then News International chief executive Rebekah Brooks attended a so-called "pyjama party" at Chequers hosted by Mr Brown's wife, Sarah. However, Mr Murdoch said relations broke down after The Sun switched its support to the Conservatives in the midst of the 2009 Labour Party Conference. The inquiry is also likely to discuss The Sun's 2006 story disclosing that Mr Brown's son Fraser was suffering from cystic fibrosis. Mr Brown has accused The Sun of being part of a "criminal-media nexus" and of illegally accessing the medical records of his infant son. Rebekah Brooks, a former NI executive, denied the story had been obtained through hacking into medical records and said the information came from a source connected to a charity for the condition. Also giving evidence this week are Nick Clegg, the Deputy Prime Minister, Ed Miliband, the Labour leader, and John Major, the former Conservative prime minister.
