The opening question asks why there were problems at Calais.

Problems at Calais. Why?

Not what to do to make it go away. I answered that opening question with a suggestion as to what I believe to be a (note: not 'the') problem. I don't know what to do to make it go away any more than I know what to do to make anyone on here go away. Other than have a few pints of real ale of course.
