SIR - The number of migrants dangerously crossing the Channel in small boats has tripled this year, according to media reports. They are twice as likely to be granted leave to remain now, rather than being sent back to the EU country where they first set foot in Europe.

Because the UK no longer has access to the EU database recording that location. It is more worth taking the risk of the crossing now.

Brexit has achieved the opposite of what many people voted for. But I'm happy for these mostly law abiding, hard working, tax paying, sociable, young people to come here. We need them.
