All Cummings did was to ratify what many think about the government's overall handling of the pandemic. While stating they were following scientific advice, they dithered and delayed, allowing the virus to spread, before finally going into lockdown weeks after being advise to do so, thereby allowing the virus to spread throughout the nation. Their performances on PPE were abysmal, despite (or because of) their awarding PPE contracts to their friends and donors. Their only saving grace is the fantastic rollout of the vaccines but even now, they are astonishingly allowing flights from India, spreading the Indian variant even wider.
Just how much truth was contained in Cumming's 7 hour session is open to question. But even if just some of it is true (and even brazen liars tell the truth some of the time) it is a damning verdict on the government. And in particular, Matt Hancock.
