I have seen it argued that it's Brexit since we left the Dublin agreement that allowed us to return people to the EU. But we hardly ever used that - in fact the figures suggest we ended up with more people returned to us than we sent "back" to EU countries.
Of course it's hard to know the truth, but I find it hard to imagine that the people in the boats and the smuggling gangs have researched the provisions of the Dublin agreement.
The majority of boat arrivals are apparently from Albania - we have a formal agreement for returning them but it doesn't seem to be deterring people from coming.
AIBU to wish there was a way for ordinary people to get hold of the truth rather than partisan opinions from all sides dressed up as pretend facts?
