With regard to the food labelling, we're participating in a research study with the Food Standards Agency that will look at the various labelling schemes in the market here in the U.K. We'll look at how they have changed people's attitudes towards foods and knowledge about them, and also whether that's changed their behaviour. They're scoping the piece of research at the moment, and it'll take 12 to 18 months. We anticipate that in about 12 months' time we should have some initial results of that large joint study.
At the same time, having introduced the scheme ourselves onto the front of manufacturers' packs, we are doing a tracking study. We did a baseline study last October and are now tracking how people's behaviour changes as a result of the labelling being introduced. We'll look at things like awareness of the label and usage of it, detailed understanding of what the label is telling them, and claimed change in their behaviour or knowledge about the food they're eating. That is ongoing. We have another wave of research happening fairly soon.
