Ministers were today asked to prove that two new rapid coronavirus tests bought to bolster Britain's war on coronavirus even work.
The tests – which give results in 90 minutes – will start being rolled out from next week. One is so simple it could soon be deployed in airports, offices, pubs and restaurants – bringing testing to the bulk of the population.
A leading scientist today suggested they should be used to regularly screen children to prevent outbreaks in schools when pupils return in September.
But, despite being hailed as 'life-saving' by Health Secretary Matt Hancock, there is no publicly available data about their effectiveness. Experts today called on Number 10 to confirm both tests are accurate by releasing research on the new devices.
Professor Jon Deeks warned mistakes in testing can put lives at risk.
