This was an inevitability:
Europol warns against fake Covid certificates
Coronavirus Global Update Europol says criminals are selling fake negative Covid test certificates, allowing people to avoid travel bans.
Talking of Covid tests ... friends of mine had their test for travel on 19th December. One hour later - Boris reversed the promises he had made and they could not travel to be with his family for Christmas. Does anyone know of any insurance covering this cost (taken before hand of course) or any action open? My guess is the govt say 'tough luck' but it is a few hundred pounds to people saving for their first house.
