Question to the Home Office:

To ask His Majesty's Government what assessment they have made of whether the "one-in, one-out" policy will lead to a sustained reduction in net migration.

The Government continues to assess the impact of the UK-France agreement as part of its wider approach to tackling illegal migration.

The agreement is helping to remove those with no right to be in the UK and supports the Government's objective of reducing illegal migration by disrupting the business model of the criminal gangs behind dangerous Channel crossings.

It forms part of a broader package of UK-France measures that is already delivering results, with small boat arrivals down over 40% this year, compared to the same period in 2025.
