It was strange to read yesterday that if we leave the EU we could lose the Calais frontier system currently in operation. This border is the result of a bilateral agreement between France and the UK which has nothing to do with the EU. France could unilaterally renounce it at any time. If she did so and we were still in the EU it would make it difficult for us as people arriving in Dover from Calais would have legal protections for their claim to reside and work here from EU law, with European Court making the final decisions. If we were outside the EU then the UK Parliament could introduce new laws like Australia’s to control the numbers.
