Thank you. I disagree with the Member that the system is a mess. We obviously understand the concerns that have been raised in relation to issues around self-isolation and household contacts within our schools. Our priority is absolutely to ensure that as many young people are in education as possible, so that we don't have the issues that you referred to in relation to home learning. We're very clear what our current position is, and this has been fed back to all the schools. I did a school visit myself, in my own constituency, on Friday, and asked the headteacher there if he felt the current guidance was clear, and he answered, 'yes'.
