This a reference to the Eat Out to Help Out scheme devised by Chancellor Sunak which resulted in 65,000 deaths. In day to day politics you forget how many died in Covid.
Perhaps he will also kill the Conservative Party off too. They make a mockery of the saying ‘success has many fathers, failure has one’. So many of them are total failures its more like sand in an hourglass, slowly passing into history like a bad dream
I think a lot of people are wary of talking about Covid for psychological reasons (or to avoid the anti-vax/lockdown arguments). Also I doubt the Tories wanted to mention it given how they handled it as a government.
