Yes, I have EU citizenship as well as UK, so can quite easily set up residence in any EU state. I am looking to speak to a professional who can advise which EU state/territory offers the best options .. or indeed further afield.
I read about Portugal, but not sure if it's still the case? I also read about some people who ensure they aren't tax resident anywhere - by not being tax resident in the UK (only paying the minimum on time spent working in the UK) and also not spending any amount of time in any other country to meet local tax thresholds.
