+xJust curious. Is it likely/possible. I did like the idea of Spain for the weather. Also wondered about living in a trailer. Cheers.
The SHPO itself won't stop you from living abroad, provided you have no foreign travel restrictions. What will be an issue, are the visa requirements for the country you are going to. Check the gov.uk website for details. Right now you can go to Spain for up to 90 days as a tourist, but staying longer than that would need a visa and that might be refused if you have a conviction. There are separate rules if you lived in Spain before Brexit as well.
If you went out to Spain as a tourist and didn't return after 90 days, then the PPU would probably notify the Spanish authorities.
