To be technically accurate Calais was not part of France until the 1580's
It was English for 250 years before that and Flemish or Boulougne before that

I can see the 'liberation' of Calais being a something the the more right wing Kippers will be proposing as a good thing to reunite the country
Nobody who's been to Calais would ever want it.
