if the definition if the uk border is in Calais port docks,or at the train terminal to the extent that once you clear French customs and drive 100 yards into the uk customs with the ensuing penalty for bringing in a trailer load of Taliban,then what happens if they swarm the fence and leg it into the uk sector? if its the uk for the truckie,why isn’t it the uk for the axle hugger? different rules to suit her majestys plobbers? if they get caught in dover,then its asylum in England,but England is apparently in Calais once you leave the French customs shed,hence theres an argument that they should be shipped into England from calais once they are in the uk shed (perish the thought) only a thought,so opinions welcome…
