Re: higher number of illegal arrivals - I can only list the numbers I find. If there's some better numbers out there, please link by all means.

But I would challenge you to ask yourself: even if the real numbers are double, or even triple - how does it compare to the 1.2 million strong legal immigration each year?

Again, I'm in favour of strong borders and countries enforcing legal immigration only. But the focus on illegal while ignoring the legal number is just weird.
