I thank my hon. Friend for being generous and giving way again. Does he recognise that the lay public’s understanding of scientific matters can also have a commercial knock-on effect? For example, tons of blueberries have been sold over the past couple of years, because they were thought to be a super-food that counteracted free radicals. More recent information suggests that they perhaps do not do that. One can envisage sales of that product plummeting and the commercial market being affected.
