On 17th March 2020, the first morning of lockdown, Peter Hennessy decided to keep a 'Corona Britain' diary. The NHS had instructed him to stay at home along with 1.5 million others deemed to be especially vulnerable and his diary became an antidote to the baffling and disturbing events that unfolded. In isolation he could not just feel but hear the connection between the bookends of the second World War and early post-war reconstruction and of Corona, as every Thursday a cacophony of clapping, cheering, singing and pots-and-pans rattling resounded around the country in support all the key workers in the front line of the battle against the virus. It was the sound of the people finding themselves once more amidst an intense, shared collective experience. By combining history and philosophy, Hennessy calls for 'a new Beveridge', a new consensus for Britain, of the scale of that built upon the blueprint laid out by the greatest social arithmetician of his age Sir William Beveridge, in his report of 1942. Hennessy believes that this new consensus will ensure that the politics and society of the next thirty years do not fall into dispiriting years of underachievement and recrimination. Understanding how the post-war duty of care was built is fundamental in helping us shape, repair and enrich post-Corona Britain.
