Last week we left a holiday park having stayed for a week. On exiting the park each car was being stopped, names taken, and the licence plate of the car recorded. This obviously was related to the corona virus, but I can't quite work out how, and why the licence plates were needed.
Obviously, I don't mind at all as if it's necessary, so be it. But I've been puzzling over this for the past few days (time on my hands!) and am now posting to see if anyone can shed light on this for me? I'm sure there's a simple explanation but it's eluding me 
Thank you!
