Dr Hilary Jones added his own voice to the discord of Boris Johnson's own scientists over the Prime Minister's 'moonshot' Covid-19 testing plan.
Speaking at a press conference at Downing Street yesterday, Johnson said that mass testing would be piloted in Salford next month, and could eventually allow a return to a 'normal life.' But minutes after he announced the plans, Chief Medical Officer Chris Whitty said the technology was not yet available, warning he should not put a date on when it would be because "that's not how science works".
The Prime Minister also said new types of testing, which are not yet available, will allow "millions" to be performed every day.
