LABOR and the Greens are expected to finalise details of a parliamentary inquiry into the media today.

A Labor caucus spokesman said talks were under way between the government and crossbenchers to arrive at acceptable terms of reference for the inquiry.

A number of Labor MPs want the inquiry to look at the concentration of ownership in the Australian media, particularly News Limited's newspaper holdings.

They argued in caucus today that News Limited newspapers distorted coverage of politics in Australia and steps should be taken to lessen concentration.

But Communications Minister Stephen Conroy told the caucus the state of media ownership was well known and should not be part of the terms of reference.

Senator Conroy said there were legitimate concerns about the ability of people to seek redress from the media and protect their privacy, which should be subject to an inquiry.

The inquiry may also look at strengthening the role of the Press Council.
