A four-metre high wall is to be built in Calais to prevent migrants from entering vehicles approaching the port.
The wall – stretching one kilometre in length – will cost €2m and be paid for by British taxpayers.
It is the latest measure to beef up security there – and prevent migrants climbing aboard lorries bound for the UK.
The UK’s Immigration minister Robert Goodwill revealed the plan as he was questioned by MPs: “We are going to start building this big new wall, very soon as part of the £17m package that we are doing with the French.”
