But we've all always known this haven't we? It's surely not news as there have been comments on GN and in other places saying that we should have locked down earlier etc.
There is a world of difference between concerned citizens discussing the management of the pandemic and a report of a Parliamentary Select Committee (in this case, two of them). One of the purposes of a Select committee is to examine government action and to hold it to account. This isn't just some grumbling citizens, it's part of the democratic 'machine'.
It focuses on the existence of the flu pandemic planning and says that it was mistaken to rely on it; presumably the SCs weren't aware of the later Exercise Alice (which has only just come to public knowledge) which was modelled on an outbreak of SARS or MERS, far more similar diseases to covd19. No doubt because the government at that time filed it away and 'forgot' about it, as they did with Cygnus. I haven't yet got far enough into the report to see if they were critical of the government for not acting on the recommendations of the report in to the Cygnus exercise (flu), which found failures in the pandemic planning.
