From the outset, we have worked extensively with retailers and Public Health England to establish best practice and publish guidance on social distancing and hygiene, to keep staff and customers safe. Industry has adapted effectively and quickly, and measures introduced include signage and floor markings to help customers maintain distance, screens at tills and limits on the number of customers in store.

I take the opportunity to pay tribute to all those key workers working throughout our food supply chain, from those working on farms to those working in logistics and food manufacturing, and of course those working in our supermarkets. They have helped to ensure that the nation has remained fed, and the work they have done has been truly phenomenal. I also agree with my hon. Friend that as we seek to evolve the current restrictions and move back to something closer to life as normal, we all have a great deal that we can learn from the measures that have been put in place by supermarkets—and also in factory environments by our food processors.

My right hon. Friend is absolutely right: our supermarket retailers acted within hours—certainly within 24 hours—to implement social distancing when lockdown occurred. They acted swiftly, and we have learned a lot along the way, in conjunction with Public Health England. I can tell my right hon. Friend that the experiences of our supermarkets and food manufacturers have been shared extensively with the Department for Business, Energy and Industrial Strategy, as it has developed safer-working protocols for other parts of the economy.
