I thank her for that question. In relation to the question of water treatment chemicals—I think she was asking about that—there have been advanced discussions with the water companies and with UK Government in relation to that so that there are contingency plans in place in relation to those that have been tested.

She's right, if I may say, to highlight the importance of food supply and food availability generally. We have been clear in focusing on that as part of our planning and making sure that we have commitments from supermarkets and distributors in order to ensure that all parts of Wales and all parts of the UK, in fact, are fairly treated in the distribution of food. We are in regular contact with local education authorities and, indeed, schools directly in relation to planning around food supply. She makes an important point, I think, which has a bearing on Brexit but has a broader bearing, doesn't it, in relation to the capacity of schools and communities to grow their own food and to ensure that people have access to fresh locally grown produce in any circumstances? But I will reassure her that, from the perspective of ensuring fair distribution and fair access of food into our public services, we are very focused on that as a priority.
