Ivan Lewis, the shadow culture secretary, today accused Jeremy Hunt of bias over News Corporation's planned takeover of BSkyB and called for the immediate publication of Ofcom's report into the matter.

Lewis, speaking at the Oxford Media Convention, also said that Labour intends to launch a policy review investigating whether the BBC could be turned into a mutual organisation with the public having a say over policy and the election of BBC Trust members.

Lewis launched a broadside against Hunt, the culture secretary, accusing him of failing to act in the public interest by continuing to sit on the media regulator's recommendation on whether the News Corp/Sky deal should be referred to the Competition Commission on media plurality grounds.

"No single voice should dominate and all significant changes of ownership should be subject to a robust public interest test," he said.

Lewis added that the process had been "further undermined by a secretary of state now charged with this decision who is on record as having a prejudicial view".

He was referring to comments Hunt made last year, before taking over Vince Cable's responsibility for deciding whether to refer the proposed deal to competition regulators, where he said he could not see much difference in News Corp taking full control of Sky.

"Jeremy Hunt could rebuild some confidence by releasing Ofcom's report with immediate effect," he said. "This would provide a basic level of transparency and clarify the legitimacy of any meetings he is having with interested parties."

Lewis also fired a shot across News Corp's bow in relation to the ongoing phone-hacking furore arguing that "no commercial interest however big or small has a right to make or break the law".

"On phone hacking it means a proper investigation by the Crown Prosecution Service and the police... until the truth is finally established and justice prevails," he said.

Lewis also said the BBC cannot "count on unconditional public support without reform". To this end he said that Labour intended to launch a review investigating the possibility of transforming the BBC into a mutual organisation.

Former culture secretary Tessa Jowell floated this idea last year but this is the first time Labour has adopted it as a firm option in the party's policy review process.

"The digital age has transformed the relationship between the media and citizens, people want more control and choice over their sources of information," Lewis said. "Public service broadcasting should respond to this new dynamic. Empowered licence fee payers could have an equal stake as members of the BBC."

Lewis added that this would ensure a "more accountable and responsive BBC".
