Explosive evidence about the tensions and disagreements between the then prime minister Boris Johnson, his ministers and the country’s top scientific advisers at key moments during the Covid-19 pandemic is expected to be made public this week at the official inquiry into the crisis. On Monday, Sir Patrick Vallance, the government’s former chief scientific adviser – whose incendiary private diary entries are being quoted selectively at the inquiry – will give evidence at an all-day session on Monday that looks certain to cast new light on the chaos in government as the virus swept across the globe.
Vallance will be followed in the witness box by the other top scientists who flanked ministers at the televised daily Covid press conferences.
