Boris Johnson rejected the Labour leader’s claim that the Government’s test, track and trace system is not yet fully operational.
Sir Keir said: “Two weeks ago today at the despatch box the Prime Minister promised that we will have a test, track and trace operation that will be ‘world-beating and yes it will be in place by June 1’.
“But it isn’t.
And a critical element, the ability of local authorities to respond to local spikes is missing.” Mr Johnson replied: “I’m afraid he’s casting aspersions on the efforts of tens of thousands of people who have set up a test, track and trace system in this country from a standing start.
“We now have 40,000 people engaged in this.”
