Door-to-door testing for the South African variant of coronavirus is to be rolled out across parts of England, after two people with no travel links to the country tested positive for the virus in Surrey.
More than 100 cases linked to the variant, known as 501Y.V2, have been discovered in the UK so far and all have been traced back to South Africa until now.
The development suggests it is spreading among local populations instead of being picked up among travellers to Britain. A similar case of community transmission has also been detected in Ealing, London.
The additional testing will be made available in parts of London, the West Midlands, and the east, southeast and north west of England.
