As well as individual evidence, Alan Rusbridger, editor at the time of the Inquiry, and other Guardian staff gave submissions on plurality of the press. A Core Participant in the Inquiry, GNM was in addition asked by the Inquiry to identify five recently published investigations which it considered to be particularly illustrative both of the value of public-interest journalism and the difficulties it can face. GNM told the Inquiry that any new system of press regulation had to consider the impact of ownership and plurality, arguing that regulation which allowed the continuing concentration of ownership in the hands of billionaire proprietors would impoverish society.
