Can I press you on the supermarkets? I think many of us are concerned as well for employees. A number of people have contacted me quite upset, overnight, who have been told that they have to go to work. It's clear that their work is not essential in any realistic way at the moment. Are there powers, or do powers exist, to enable either this Government here or the United Kingdom Government to take action and to protect those employees from future actions from unscrupulous employers?
