I thank my hon. Friend and a number of other colleagues for continuing to campaign on and raise these important issues. As parents and Constituency MPs, we all see the damage that social media and unmitigated use of smartphones can cause to teenagers. He is absolutely right to highlight that schools already have the power to confiscate smartphones, and I am really pleased to hear that a couple of schools in his constituency have done so. We will continue to monitor the effectiveness of the guidance that we have issued, but I implore schools and parents to take a much more proactive approach in monitoring what children are up to on their smartphones.
