Talking of tools at my hon. Friend’s disposal, Bournemouth University stands ready to help with lab testing. However, it is covid testing in schools that I would like to address. Today the rules state that the entire year group must stay out of school for 14 days if one of the pupils in it tests positive. That causes huge disruption not only to learning, but to working parents, who have to provide childcare. With better testing systems now in place, please can we review this 14-day rule that sends entire year groups home, so that we can keep children both safe and in school?
