Gilles Debove, a Calais police union spokesman, said about 200 mainly British "No Borders agitators" were in the area when migrants stormed a ferry last month, reportedly at the urging of the activists. “They (the activists) come and help the migrants but they also manipulate them. They should not be inciting migrants to break French law. If they want to demonstrate, they should do it in England,” Mr Debove told the Telegraph.
