I agree with my hon. Friend. We are determined to proceed with this in an evidence-led way, and we will be engaging with experts in the field. On Friday, the Under-Secretary of State for Health and Social Care, my hon. Friend Jo Churchill, and I held a virtual roundtable on these issues with a number of public health consultants and leading academics in this field, including Professor Michael Marmot. I am very grateful for their input. We intend to continue in this spirit by engaging with other experts such as the Office for National Statistics.
