UK Borders Bill

Then why cannot the noble Lord produce those opinions? Let us hear them. It is getting a bit late; we have only a couple of minutes; we are under pressure from the clock. Before I finish, I want to challenge the noble Lord’s assertion that there had been enormous advances in medical and technological assessment of age by the use of X-rays. That simply is not true.

[Amendment No. 44 not moved.] Clause 21 [Assaulting an immigration officer: offence]: [Amendments Nos. 45 to 48 not moved.]
