Coronavirus Bill

I thank the Secretary of State for giving way. He is being incredibly generous. Clause 23 talks about food supply chains, which are absolutely crucial. He will have seen that many supermarkets are taking on additional workers to meet demand. Can he provide an answer on this point or get one from the Treasury? I have heard from many people who are thinking of applying for those jobs, perhaps to make up loss of income. If they are covered by the 80% wage subsidy, are they able to take on extra work or will they lose the 80% wage subsidy from their existing job? May we have urgent clarity on that point, because it could be deterring people from taking up those important jobs in our supermarkets and supply chains?
