Very rarely do we come across a cache of documents giving an unvarnished glimpse of the personalities, as well as the policies, which shape our lives. Britain's 30-year rule shows us memos and scribbled comments, but with no hint of the conversations behind them. Richard Crossman's posthumous diaries were so explosive that ministers tried to suppress publication, but even that was just one man's view. Matt Hancock won't be thanked for it, but he has done the nation a great service by keeping perhaps the richest documentary source disclosed in recent years.
Conversations in and around 10 Downing Street would never normally be recorded. But Hancock's WhatsApp messages offer a real-time record of decision-making - complete with gossip, reactions, documents, conversations and emojis. They have several stories, to be sure, but the real value lies in something greater:
a psychological profile of a group of men who had untrammelled power over the lives of millions. How would any group behave, in such circumstances?
The Lockdown Files let us find out.
After reading thousands of these messages, the big theme is far more than the sum of the scandals. There's no end of those. At one stage we see that a convicted sex offender is suggested to bankroll a Matt Hancock leadership bid - which, it's explained, would be fine because he's a "lovely" chap who went to St Paul's and is "regarded fondly". There's plenty more chaos and skullduggery to be exposed in coming days. But the real value in The Lockdown Files lies in far more than the sum of the headlines.
