These are the marks I would give to the Prime Ministers in my lifetime (that I have a memory of) for competence and commitment. They may seem high but I think these people work incredibly hard and have the nations interests at heart. Until now Thatcher 10, 10, Major 8, 10 Blair 10,10 Brown 8,10 Cameron 8, 10 May 7, 10 Boris 2, 2 Intelligent people or papers (Telegraph ) who back him, won't be judged well by history imho. Like the Republicans for getting behind Trump.
