I criticise government failure to act on information, reports and to ignore warnings of danger, especially when, as in this case, it has let to numerous horrible deaths. I don't really believe you have any objection to that. You're just uncomfortable that the government responsible for failure is a tory one.
There's not much chance that I will spend my time criticising the actions of Gladstone or Disraeli or other governments of the past.
Is it Friday? If Chancellor Osborne says "My understanding is that it is Friday" do you believe him?
