Here is a comment, reported in The Guardian and attributed to an un-named member of the Government Advisory Group, SAGE:

“This government has failed to show any self-criticism whatsoever, when it is glaringly obvious to everybody that big mistakes have been made. If you want the trust of the population you hold up your hand and you say ‘we’ve made these mistakes, this is why they happened, we regret it, we’re learning from it’. Rather than just keep saying ‘we’ve done the most fantastic job’ and not being open to criticism in any way.”

It speaks for itself.
