We don't know what will be lost, until it's done! To say that the UK will collapse and require a bail out like the republic got is silly... if ni ends up with food banks that are unable to feed people and charge people£50 to have a doctors appointment (normally the done thing down South) then I think we'll be in the shit... at the minute Britain has actually improved lately as companies continue to invest and deal with Britain.. globally countries will continue to do what's best for them as will companies...
Another nonsense post. Nobody, or at least few people, are saying that the UK will collapse (although Scotland might leave and the peace settlement in NI might collapse). They are saying that the economy will be less in 5 years time than it would otherwise have been, with a great deal of pointless disruption caused in the meantime. Companies will do what is best for them, and this xenophobia driven project is not good for a lot of them.
And alluding to a different system of charging for doctors, as is it was somehow relevant, is just immature.
