Does anyone know if this has happened and if so what action did the individual and authorities take?
Imagine: you’re both feeling great, you’ve checked out of your hotel, got to the airport in plenty of time to do the test and catch your flight. You take the test, wait around and then to your horror you get a text stating that one of you is positive. It would be impractical that one of you returns to UK and the other remains.
What can you do? What help can you get and from whom? Where would you quarantine etc?
