We granted almost 100,000 arrivals via legal routes so again, nonsense.
We are not a preferred destination, that's not what I am saying. We do have a number of favourable conditions for asylum seekers which is why some people attempt to cross the Channel from the relative safety of France. There's never going to be one single reason but the asylum regime in the UK is a clear factor in the decision. It's difficult to collect stats on illegal migrants for obvious reasons but the Oxford Migration Observatory reckons the main reasons people continue on to the UK from Europe are family ties (clearly), English language, and perception of the UK as a friendly environment for asylum seekers. But the research they cite to come to that conclusion is over 20 years old so pretty much useless.
Our mix of nationalities is fairly in line with the rest of Europe with Afghanistan being the most common origin for us and Syria for Europe, of which both have a near 100% approval rate. It's Spain that's the outlier, not us.
