All travellers arriving in the UK will have to take two coronavirus tests in a fresh attempt to prevent mutant strains entering the country under new rules to be announced this week.

The UK's Department for Health and Social Care (DHSC) said the move was designed to provide a “further level of protection” enabling the authorities to track new cases more effectively.
