@dolphinprincess1 The Kent coastline alone is over 200 miles. Border Force has 5 cutters and only 1 available on SE coast (they have another 19,000+ miles of coast to protect). Their responsibility is not just people trafficking but also drugs, weapons, money etc etc.
Britain, with a plethora of suitable beaches has always been a nation of smugglers and smuggling. This is a concerted and very organised effort by smuggling gangs. We will only counter it with assistance from the French. Ironically our leaving the EU may yet make Border Forces job harder not easier.
