EU not expected to be on UK Green List when international travel resumes.
This may be of interest to some. Reports are coming out of the UK saying that the government has announced the traffic light list for countries won't be released until one week before international travel resumes and that the EU is not expected to be green. Meaning, you will need to quarantine, either in a hotel (red) or at home (amber) if you plan to visit Spain.
Things can and will change, but that is the initial state expected in the short term. Plus, of course, you need to wait for Spain to allow tourists in.
