Some countries have changed the travel restrictions due to Delta variant

Portugal, Spain and Germany have issued new travel restrictions in a bid to limit the spread of the more contagious Delta coronavirus variant, which was first detected in India.

Germany began implementing new restrictions on people entering the country from Portugal and Russia on Tuesday, involving a two-week quarantine.

Meanwhile the UK is under the spotlight given rising numbers of new coronavirus cases with the Delta variant. German Chancellor Angela Merkel has expressed her concern over the Euro 2020 tournament, her government calling for crowds at British stadiums hosting matches to be reduced.

As of Monday (June 28), non-vaccinated Britons travelling to Portugal need to go through mandatory quarantine for two weeks, according to an order published by the Portuguese government.

Under the new rules, anyone travelling to mainland Portugal by air, land or sea, has to prove they have been fully vaccinated or have to isolate.

The measure comes after Merkel criticised Portugal last week for allowing British tourists to travel to the country between mid-May and early June, while the Delta variant was circulating in the UK.
