“I think when it comes to trying to make sure that we give maximum confidence to businesses and customers in the UK, there are three things – there’s immunity whether you have had it before so you have natural antibodies, whether you have been vaccinated, and of course whether you have had a test.

Currently, foreign travel for leisure purposes is illegal under UK lockdown regulations.
