?Dangerous monopoly?: Labor and Greens support judicial inquiry into media diversity and News Corp

Labor and the Greens have recommended a judicial inquiry with the powers of a royal commission into media diversity, ownership and regulation.

The majority report from the long-running Senate inquiry into media diversity found it was "clear that the current regulatory framework is not fit for purpose and significant changes are required".

"A judicial inquiry would have the capacity for a more comprehensive investigation, including compelling witnesses to give evidence, than can be undertaken by a parliamentary committee," the report, which was tabled on Thursday, stated.

"Such an inquiry would also be conducted at arm's length of all politicians to allow an independent investigation into media regulation and ownership."

Greens senator Sarah Hanson-Young won support to set up the Senate inquiry a year ago following the popularity of Kevin Rudd's petition for a royal commission into Murdoch media.

The former Labor prime minister's petition for a royal commission into the need for a strong and diverse media was supported by more than 500,000 people.

Rudd subsequently criticised Rowland on ABC TV by suggesting she was too "close" to Murdoch.
