TOP UK food firms are launching a £4million campaign promoting nutrition labels which do not follow the official food watchdog's advice.

The drive to publicise Guideline Daily Amount labels starts on Monday.

It could go head-to-head with a Food Standards Agency campaign promoting "traffic light" labels.

The food watchdog wants red, amber and green to show levels of fat, saturated fat, sugar and salt in foods.

But manufacturers and retailers rejected the traffic light scheme in favour of the GDA system.
