Blame for the ridiculous situation cannot be laid at MAG's feet, but at those of Her Majesty's Government and their mindless pampering to the xenophobic tendencies of the Daily Mail, Telegraph, Express et al who can't bear the thought of people crossing the UK border in the same, uncomplicated way that they do virtually all other (western) european borders.
With the level of border control that people in UK (seem to) want the price is delays, delays and more delays.
Key difference being there's millions more displaced young men who want to come here mate. Look at Sangatte, the reason the UK is a magnet for randoms to vanish into the black economy is that there's enough Africans,Pakistanis, Iraqis and Afghans here already that can support them quite against the law. Not quite the same in rural Belgium now is it? If you have an out of control immigration policy, you're not going to fix that with open borders!
We all need to be careful what we wish for. The existance of the camp at Sangatte is all the evidence that is needed that France's borders are clearly not secure.
France is a member of the Schengen arrangements.........
Another reason that the UK is a magnet is the English language, most of these chaps have at least some English as a second language.
