I totally agree with your first paragraph, unfortunately I cannot see how it will ever work when we are so reluctant to remove.What we want is some sort of treaty whereby a failed asylum application anywhere in the EU is also effective as a failed application here.
The UK being the next application post is killing us on illegals.
If this is a step in that direction, and the price is not too prohibitive, then anyone who claims to oppose illegal immigration will need to be ready with their argument that these proposed measures should also be opposed.
