(BBC) The Ministry of Defence said 606 people crossed the English Channel in 12 small boats on Wednesday.
It means 21,164 people have made the crossing so far this year, compared to 28,461 in the whole of 2021.
The French authorities said another 101 people were returned to Boulogne and Dunkirk after they got into difficulty.
The government described the rise in Channel crossings as “unacceptable,” and said asylum seekers should apply in the first safe country they reach.
By crossing the Channel, the government said, people were “risking their lives and lining the pockets of ruthless criminal gangs.”
