While we await what is likely to be the coronation of Andy Burnham, we might wonder how it is that in the ten years since the Brexit vote were about to have in the UK our seventh PM... that one every 20 months (on average, some lasted a little less, some a bit longer)?

There are a range of reasons, perhaps most importantly rebellious (impatient) MPs, but it also a job that is difficult to succeed at when the underlying political economic conditions in the UK are so 'challenging'!
