An attack by the CWS on TV advertising that "blackmails" children has been dismissed as an empty gesture by the food industry. The retailer says it will no longer advertise products high in fat, sugar and salt during hours when children are watching TV. It has called on the ITC to introduce restrictions that would make the food industry follow its lead. But the Food and Drink Federation said retailers rarely advertised individual products. Codes of Practice already exist governing children's ads, said the FDF. Parents in Sweden, where advertising to children is banned, complain more about pester power than parents in Spain where it is unregulated, the FDF added. The blackmail inquiry' is the first of a series to follow the Co-op's Food Crimes report in May. {{NEWS }}
