[Gordon Henderson in the Chair]

Before we begin, Dr Johnson wants to declare an interest.

I am a consultant paediatrician in the NHS and a member of the Royal College of Paediatrics and Child Health, and one of the witnesses this afternoon—Mark Rowland—is known to me.

If anyone else wants to declare an interest, please do so now.

I declare an interest as a member of the responsible vaping all-party parliamentary group.

Thank you.
