One man has died and about 30 other people have been rescued in the Channel after their boat ran into difficulties while trying to cross from northern France to Britain on Friday, prosecutors said.

The victim is believed to be in his 20s and to be of Sudanese origin, the prosecutor’s office in Boulogne-sur-Mer said, adding that the others had been rescued in waters off the village of Berck.

A record 28,000 migrants crossed the Channel from France to the UK in small boats last year, according to a tally from the Press Association, causing major diplomatic tensions between the neighbours.

At least 27 people died on November 24, the deadliest disaster since migrants began taking to the water in large numbers instead of trying to stow away in trucks or cars travelling between the countries.
