Mike, Sorry mate I cannot remember exactly where I saw this BUT I clearly remember thinking ‘wow’ something advantageous from the tax system and also that it was a reliable source.
If you think about it what claim on the money would the UK have? - it was not ‘earnt’ there - the more amazing thing is that Spain lets you walk away with it but I suppose that is an EU benefit.
But take professional advice and I am sure they will bear me out.
If I come across the info again I will contact you.
For anyone else - I guess this only applies within the EU (not USA, Canada etc - don’t know)
