UK testing – latest
Yesterday it was announced that the UK issued 76,496 tests in 24 hours, falling short of the 100,000 daily target.
Speaking in the daily press conference yesterday, Michael Gove, the Cabinet Office minister, said 76,496 daily tests had been undertaken in the 24 hours up to 9am on May 3.
This compares to the 122,347 tests carried out in the 24 hours to 9am on May 1 — the target period for when Matt Hancock, the health secretary, had set a deadline of undertaking 100,000.
