The director of the Migration Observatory at Oxford University has said it is “really difficult” to say why the number of small boats crossing the English Channel has decreased in 2023.

Madeleine Sumption said: “Policy is one factor that affects the number of people, but it’s usually not the most important.” Report by Jonesia.
