Portugal is stopping flights to and from the United Kingdom from Saturday, blaming a Covid-19 variant first identified in the UK for a surge in new Portuguese cases.
The move comes a week after the British Government halted flights to and from Portugal in an effort to prevent a variant found in Brazil from reaching the UK.
The Portuguese government labelled that decision “absurd”.
Portugal has the highest seven-day average rate in the world of new cases per 100,000 population and the highest rate of new deaths, according to data collated through to Thursday by Johns Hopkins University.
Tens of thousands of British people, often retirees, reside in Portugal, while hundreds of thousands of Portuguese have gone to work in Britain in recent years.
Portugal blames the rise on the appearance of a more contagious variant first identified in south-east England.
