I know that, for someone who has been an opportunist all his life, this is difficult to understand, but having read and considered the SAGE advice, I have genuinely concluded that a circuit break is in the national interest—genuinely concluded. It is the failure of the Prime Minister’s strategy that means tougher measures are now unavoidable. That is SAGE’s view. SAGE has advised that a circuit breaker should act to reduce R below 1, should reset the incidence of disease to a lower level and should set the epidemic back by approximately 28 days or more. All three are vital, and that is why Labour backs it, so can the Prime Minister tell us what is his alternative plan to get R below 1?
