The requirement for ALL returning travellers to the UK to have a PCR test abroad, 3 days before they arrive back home seems to be a showstopper. I have found 2 clinics that offer this service, both in Corfu Town. That's an expensive round trip in a taxi, so I'm hoping this issue is being looked at, with a view to providing either group transport to a suitable accredited clinic, or, some mobile testing facility where tests can be taken locally, and then transported to a central facility for analysis. Until some positive news about this mandatory requirement for all UK visitors is forthcoming, people will simply won't travel. This PCR test also applies should Greece get placed on the Green list.....so you could say its rather an important issue, one that will last all summer. Jon B.
