space the systemic failures occurred on the Tories watch. He's the PM, the buck stops with him and those who serve under him. If the system failed, it was his party's system. They had over a decade to sort it. Same as with social care, welfare, schools, law and order etc.
The pandemic was handled under him. He was in charge of the handling. You talk about rearranging words, I could be here all day saying it in different ways, but if there's a pandemic and you are the PM, you are ultimately the one who is accountable as are those you appoint. And he appointed Cummings. And Hancock. And Gove. Again, I could go on.
