"But,of course, you EU haters will never face the truth !! "
Well here's a few truths to be going on with, brionon.
The truth is that one of the EU's founding and most important principles is the free movement of goods, capital and labour. A result of this was that "labour" was quickly interpreted as "people" and people were allowed to move across the continent whether they were providing labour or not. This saw the borders between continental mainland EU nations all but disappear.
In 1985 this situation was reinforced when the ridiculous Schengen Agreement was signed (which, thankfully the UK declined to do). This effectively made mainland Europe (the EU nations plus one or two others) a single area as far as immigration and travel was concerned and once in that area people face no borders whatsoever.
Immigrants seeking to settle in Europe arriving from many African nations usually travel via north Africa and land in either Malta or (more usually) southern Italy. The Italians welcome them (they are "proud" to be the landing point of choice for these hapless souls). Unfortunately they are not so proud as to want to keep them and they are quickly ushered across the unmanned border into France. Those wishing to reach Utopian UK travel freely up to Calais and the French suffer the problem there we see today.
The truth is that France is suffering this problem because (a) it belongs to the EU (b) it is a signatory to the Schengen Agreement and (c) it does not insist that Italy meets its obligations to offer asylum to these immigrants as the first safe country in which they land. Suggesting that this is a problem to be tackled by the UK is completely unjustified.
They are the inconvenient "truths" of which EU haters are well aware.
