Portugal Questions UK's Decision To Remove It From Safe Travel List Tourism operators say Britain tourists start 'tsunami of cancellations' to avoid compulsory 10 day quarantine. The Portuguese government has questioned the UK's decision to remove Portugal from its safe holiday destinations list, which has sent shockwaves through the country's tourism industry. "We take note of the British decision to remove Portugal from the travel 'green list,' the logic of which we cannot understand. Portugal continues to carry out its prudent and gradual de-confinement plan, with clear rules for the safety of those who live here and those who visit us," Minister of State for Foreign Affairs Augusto Santos Silva said in a statement late Thursday.
