Britons holidaying in the Algarve as the UK government put Portugal back on its 'amber' travel list were confused and frustrated at the prospect of booking more tests and facing a 10-day quarantine upon returning home.

"They give us the green light so we can come here, we go through all of the procedures to come here, and then they do this and I just think it's really, really wrong," said Jasmine, visiting from Bristol.

Britons returning from Portugal from Tuesday onwards will need to quarantine for 10 days and take two Covid-19 tests. Under green list rules, travellers would only need to take one test and did not need to quarantine.
