I live in UK, naturalised British at eight years of age (now 40s), but post-Brexit I’d like to maintain my rights as an EU citizen.

I’m thus considering doing what is know as “recovering” my Spanish citizenship “by origin” (which has been confirmed I’m eligible to do).

The questions in my mind are:

1) I’m told Spain requires me to renounce my UK citizenship - but so far as I understand it that is for Spain’s own purpose only. They would consider me Spanish only, but UK would consider me a dual-national. Would Spain have the right to retain or invalidate my passport at the Spanish consulate?

2) I’m told I have to go to the Spanish consulate in London, but I have no idea what such a meeting will entail?

3) Are there tax implications?

4) I don’t intend to live in Spain anytime soon - would it be better to just wait to see how rEU/UK relations go, or just go for it now?

5) Anyone else here gone this route?
