With all this talk of a second successive unelected Prime Minister, I wondered to myself When was the last occurrence in peacetime that a Prime Minister was replaced twice between elections?
I think that the only time was way back in 1742 when Spencer Compton took over from Walpole before dying the next year, but that doesn't really count as it couldn't be avoided. Neville Chamberlain and Winston Churchill is another example, but that doesn't count as it was in wartime.
Does anyone have any other examples? If not, we could be heading for a unique situation in modern day politics. Although, I still think Labour would be mad to do it.
