Britain's medical regulator has accused ministers of 'stretching' its approval of controversial lateral flow tests for coronavirus.
The Medicines and Healthcare products Regulatory Agency (MHRA) warned the way they are currently being used risks infected people assuming they are clear and safe to mingle with others.
Regulators approved the controversial kits - which give a result in under half an hour - to be used as a way to find Covid cases, helping to keep schools and workplaces Covid-free after lockdown.
But due to fears about the accuracy of the tests, the MHRA stressed they were not to be seen as a 'green light' for those who test negative to enjoy greater freedoms.
