Newsagents marched on Downing Street this week to hand over a petition calling for a referral of the newspaper and magazine industry to the Compe-tition Commission for a full investigation.

The petition was signed by more than 20,000 people and delivered by National Federation of Retail Newsagents' national president Kieran McDonnell. It is part of NFRN's Press for Reform campaign, which is calling on the Commission to assess how "publishers fix prices and margins and ­create monopoly distribution arrangements that threaten the survival of small stores".
