Where did you get this from, Gromit ... I can't see it in the link in the OP or in NJ's Standard article:
> The figures for April 2022 mean the total number of migrants to arrive so far this year is 6,693 across 204 boats.
> Some 1,425 of these had made it across since the Royal Navy took over control of migrant operations in the Channel on April 14. //
If those numbers are correct then that's 1,425 in the two weeks since the deal was done with Rwanda, 21% of the 6,693 for the whole year to date ...
