BS on brexhit for sure, he had the luxury of not being in power, and prepared two versions of a decision, one remain, one leave, and was driven by self interest and a degree of vengeance.
But being in power meant he was propelled to act reasonably sensibly by the more objective scientific advisers and civil servants. I don't believe the country would have been better prepared under other governments/leaders because emergency planning was never a budget priority. Insufficient hospital beds, ventilators etc was a national problem successive governments had ignored. Our strength as a country was to react well to emergencies but be poor in planning for them
