I think you may find he was being facetious.....
Metro (owned by the Mail) this morning stated that net immigration from outside the EU is over 200,000. These are the immigants we already have absolute control over, because that are from outside the EU (see what I dd there?). So why can't we control our borders now, and how will anything change after Brexit?
Its all bullshit. It always was all bullshit. Even Gove today admitted that the scare story he supported about hoards or Turks streaming into the UK because Turkey was about to join the EU was bollocks (his actual words were, to paraphrase, 'possibly missjudged, but hey ho').
But anyway....lets all work together and make Brexit work, eh?
I did realise that he was being sarky, just thought I'd reply anyway! And I realise you're too, but my response to your last sentence is "why?? We didn't vote for it so why the feck do we have to help these dreamers reach their utopia?
