Yes it'll take quite a lot of planning, not least mixed race families dotted here and there around the globe. Take a white Brit who's married a black African living in Africa with two kids. The Brit will need to come back here as part of the mandatory policy requirements, the black wife will need to remain in Africa. As for the kids, MMmmm difficult one. Maybe a country should be given over to 'the mixed race' as they neither fit into the distinctly black or white categories. That's where I'll be destined for.Quite a lot of Americans and Europeans have colonised North Africa in the last 70 years and more.
Good to see Regan supports sending them all bsck.
However with planning it can be done. As I say, get Farage et al on the case, I'm sure they'll have all the answers.
