Sainsbury's-Asda deal risks environmental harm, say campaigners

Regulators told shortcuts may be taken as pressure grows on producers from price cuts

The proposed merger of Sainsbury's and Asda puts too much power in the hands of large retailers and will have a damaging impact on the environment, regulators have been warned.

Food campaigners, environmentalists and farmers' leaders are claiming the proposed deal, and the accompanying promise to further drive down prices, will put more pressure on producers, many of which may be forced to cut corners on environmental safeguards and shelve green initiatives.
