What is so complicated about having a processing centre in Calais as offered by France? That way the vast majority of refugees whose applications for asylum are approved could arrive in the UK ready and willing to find work and become huge benefit to the country.
In many cases they have family links here. Built in support systems. The insanity of the Rwanda idea is that it is designed to stop traffickers. By punishing the victims who would be deported without being heard, even though the majority would be granted asylum? The refugees?
