It brings the overall number of migrant crossings this year to 14,808, an unprecedented figure despite several measures in place by the French and UK governments to curb the crossings.
French coastal authorities said they also rescued nearly 200 migrants between late Friday and late Saturday.
The latest crossings, which UK Defence Secretary John Healey described as “shocking”, fall short of the all-time record of 1,300 migrants arriving on small boats in a day in September 2022.
But they will still prove a headache for UK Prime Minister Keir Starmer, who has been at pains to toughen his rhetoric on irregular immigration amid pressure from the far right to slash migrant numbers.
“We all want to end dangerous small boat crossings, which threaten lives and undermine our border security,” the Home Office said in a statement on the latest arrivals.
