The group, made up of about 150 MPs, is investigating complaints of unfair dominance of retailing by grocery and non-food multiples as it fears a cloning of the high street.
Its High Street UK 2015 inquiry planned to present evidence to the OFT in the autumn with the hope of initiating a full market review. Evidence hearings will now start in October. A spokesman for the group said: “Far too many people want to send us information but have said that they cannot meet the deadline.”
Association of Convenience Stores spokesman James Lowman said that the inquiry had reignited people’s interest in a full market review, for which the association has campaigned.
