From a House of Commons report assessing 2022.
‘The UK–France Joint Leaders’ Declaration issued in March 2023 states that France prevented 1,381 small boat crossings, carrying 33,788 people, in 2022. This equates to 42.4% of attempts to cross and 55% of small boats being intercepted by the French authorities in 2022.
The UK Government has said that “at least” 59 Organised Crime Groups connected to Channel crossings have been dismantled, and over 500 arrests made, since the foundation of the UK–French Joint Intelligence Cell in July 2020.’
Since then funding has been increased. I would suggest that this is more than a ‘token’ effort and that stopping all crossings is all but impossible and that the French and UK authorities put in a lot of time and effort.
