No doubt, but it can't be cheaper than how Australia deal with potential migrants with HIV.
Ask the British taxpayer what alternative they would prefer.......
A) Unlimited NHS costs to treat migrants with HIV for free, or
B) Refuse entry if they pose an unreasonable cost to the taxpayer.
Remind me, who's interests are MPs serving?
You tell me. You brought this up, and brought up just one part of the picture. I have asked you a number of times now, to provide the overall cost benefit but you continue to ignore this and plough other, possibly face saving, fields. And yet again you provide nothing more than supposition.
If you come up with some facts and figures, like the UK figure mentioned above, and also the Aussie figure, I'll view them and let you know my answer. Until then I'm happy to run with a program which numerous PMs have followed.
