More about PM’s mandates

I have from time to time reviewed the politics and history of how Britiain’s post-war prime ministers came to power. Earlier today I was reminded of my surprise at school on learning of how Von Papen replaced Brüning ,wondering how someone from the same side could succeed someone who had lost a vote of no-confidence. At the time in the UK, party government was secure and sectarian, although this was about to change.  I published a model in an article called “Mandates” and revised it in an article, ‘PMs and “coronations”’, in which I looked at Theresa May’s record, which caused my model problems of definition. I was inclined to believe that now both the major parties have “primary” leadership elections, party coronations are not successful. May is a case in point while Johnson had to fight a member’s ballot. Anyway, as this Tory administration reaches, what if there were any justice, its denouement, here’s what the chart looks like today.

It only shows those leaders who became prime minister; politics may have changed to the point where we need to include those leaders who lost elections as well.

I first explored this in 2010 when the press were claiming that Gordon Brown was squatting in No. 10 after they had monstered him for not seeking a mandate in 2008. Good politics might suggest that he should have done so.
