And once levelled up, people will return back to their home.It's called levelling up. Nobody wants to see a Poland brain-drain. They want FoM, of course, but they don't want Poland empty and nobody to mend the roads. So you do both.
Someone should explain to Boris what levelling-up means. The probelm is that Boris and his pals don't know where Barnsley and Bolton are on a map, much less know what they look like, so making them reasonably prosperous is about as likely as London falling into the sea next week. It is of course possible, but there is millions of pounds invested to make sure it doesn't happen.
So where do our fruit and veg pickers come from then? Was it all a temporary fix?
When I was last in Poland the complaint was about the cheaper Ukrainians coming in for jobs. It seemed rather ironic.
I can understand why Poland joined the Union though. They have been a country pulled around for the last 150 years by their neighbours.
