Covid-19: Portugal removed from UK's 'green list' over virus mutation risk

London - British PM warned the travel industry that protecting the country's vaccine roll-out was his priority.

Britain has removed Portugal from its quarantine-free travel list, the country's transport minister said on Thursday, essentially shutting down the UK's leisure travel market and deepening the pandemic crisis for airlines.

Airline easyJet also said no new countries would be added to the so-called green list.

Britain relaunched travel on May 17 following more than four months of lockdown, with Portugal the only big destination open to UK travellers.

Transport Minister Grant Shapps told reporters that Portugal would be moved to the amber list due to rising Covid-19 case numbers and the risk of a mutation of the virus variant first discovered in India.

Over the last three weeks, Portugal has proved a lifeline for airlines and travel companies. The industry had been expecting a wider reopening this month, but instead will face weeks of cancellations and more uncertainty.

"This decision essentially cuts the UK off from the rest of the world," easyJet said in an emailed statement.

The airline also said that the UK would be left behind as governments across Europe start to open up travel.

Shares in easyJet and British Airways-owner IAG and Jet2 were down 5 per cent while Ryanair and TUI , which has a big German customer base as well as British, lost 4 per cent on fears that Europe would lose another peak travel season, when millions of Britons usually head to southern Europe in July and August.

The industry is already weakened by 15 months of lockdowns and it will be severely financially challenged if there is no reopening this summer.

Many companies had hoped for bumper trading given that Britain has one of Europe's highest vaccination rates and is gradually reopening its domestic economy.
