Does the right hon. Gentleman agree that there should be sufficient encouragement for the owners of tanning salons to ensure that they have sufficient proof of age? We know that some people under the age of 18 may be attracted to use such machines and have been able to do so until now. It is quite difficult these days to work out whether young people aged 16 or 17 are under the age of 18. However, to take away that possibility, if people are in doubt and think that someone may be under 18, even though they look 25, they should show proof of age.
