Four people died trying to cross the Channel overnight after the busiest day for small-boat crossings so far this year saw 752 arrivals in the UK. One man died after a vessel capsized off France's northern coast late on Wednesday, local officials said, with a one-year-old child among those hurt. Seven hours later, three people were found dead aboard a small boat after launching from Dunkirk overnight, some 100km (62 miles) up the coast. French officials confirmed their deaths as the Home Office reported that Wednesday saw the highest number of crossings in a single day this year, with nine boats reaching the UK. Prime Minister Andy Burnham, speaking separately about small boat crossings on Thursday, said the UK had made "significant progress" on reducing the number of arrivals.
