What a coincidence then that boat crossings shot up, exactly as we left the EU in 2021.
Prior to this, the feeling was that there was no point in giving yourself up to the authorities, as one could be returned... once we lost this, open season on turning up at the border ensued.
That was the deterrent we had, which people who voted for Brexit took away.... it doesn't matter we didn't send back everyone, the fact was it was too big a risk to take.
But i don't expect Brexit supporters to acknowledge this, few will ever accept they were duped, infact they double down and now back Reform
"Fool me once, shame you, Fool twice...." was never so true!
