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."
