durhamjen, we wouldn't need to leave Calais to watch our borders. This was an arrangement between France and UK, not an European one. The big problem in the Kent ports is the volume of traffic, the number of illegals coming over with/out connivance of lorry drivers, the acute shortage of border guards and finally the problems with the number of illegals, especially minors "stuck" in Kent. No-one wants the! It is tragic.
But I shall still vote out - the euro is on the point of collapse and we don't want to catch the flotsam, and I don't think that Europe and become a Federation due to the extraordinary difference in the different philosophies that make up the governments, from Marxist and Kantian to Utilitarian!
