Some asylum seekers will be sent back across Channel for first time under treaty agreed with French president

The UK will begin detaining people who arrive on small boats and returning some to France “within days” after the EU gave the green light to a deal agreed with the French president, Emmanuel Macron.

The treaty between France and the UK will allow the Home Office to return some asylum seekers back across the Channel for the first time in exchange for accepting others directly from France via a safe route.

Those who have crossed the Channel to the UK using small boats will become inadmissible for safe routes, according to the terms of the treaty. About 50 people a week are expected to be returned during the pilot of the so-called “one in, one out” scheme.

The Home Office said the pilot was “operationally ready” and that detentions could start within days. The summer months, when the weather tends to be better, are usually the high point for crossings, with 898 arrivals on 30 July alone.
