Without knowing on what basis they made that remark, it's quite difficult to answer. Truly, it is too early to say it isn't working in the U.K., and it's equally too early to say it is. But some of the anecdotal information we have is showing changes in consumer purchasing behaviour in a healthier direction. Equally important is the point Gill made at the beginning that in everything we're doing in this area we're trying to institute systems that include incentives for industry to reformulate in a healthier direction, and there is some evidence of that happening.
If, for example, you're producing a ready meal that would have four red lights on it, there is quite a strong incentive on you as a retailer to try to change that to four amber lights, or maybe even two green lights and two amber ones. We have some evidence of that happening, and that is as important a part of what we're doing as trying to change consumer behaviour.
