I really don't understand the logic of this "open the boarders" patter.
I assume you agree that they would need to have their freedoms restricted until such checks have been carried out. How do you propose this is done?
Plenty of immigration centres in the UK.
Or takeover a few hotels.

If they are genuine, paperwork won't take long, apparently so I have been told on here.
So real refugees will not need to be kept long.
It is 99% women and kids anyway, as all the fighting age men and boys are left in Ukraine.
