Health minister Helen Whately defended the UK’s coronavirus testing regime following growing calls for the country to hugely expand its programme.
She told Sky News the country is “right at the top of the league table” for COVID-19 testing – despite admitting countries such as South Korea and Germany have conducted a much greater number of tests.
The World Health Organisation has previously called on national governments to “test, test, test” as the “backbone” of the global response to the coronavirus pandemic.
