As a member of the Select Committee, the hon. Gentleman will be aware that in April last year, we discussed at the Select Committee health measures at the border and the work of the Government. In terms of the effectiveness of the measures, he will be very familiar with all the measures—the statutory instruments, the regulations and the directions to airports, Border Force and the ports. As I and other members of the Government have said throughout, and particularly today, all measures are under review, and that is the right thing to do.
