SBP-cooperator ....I don't understand what you are suggesting?
Why on earth should Scotland returning to her previous, normal state of independence (which she was for hundreds of years before England managed to get itself together, form a nation) have a requirement for everyone in the (former) UK to have dual nationality?
Dual nationality of which nations?
Scotland is a welcoming country, we encourage migrants to come here, help our country to grow and thrive - BUT I think it unlikely that we would trust Boris Johnstone, Jacob Rees Mogg, Michael Gove (yes I know he was born in Scotland)or any of their ilk to set foot on our soil!
(Have you watched / listened to the abuse SNP politicians receive from the Tory benches in Westminster? ?
