Earlier this week Prime Minister Scott Morrison called a late-night party room meeting to talk about leadership spills.

The rule changes shore up his position, by making it harder to knife a sitting prime minister.
So, given this happens so often, it's worth examining the rules. How do the major parties decide on who will lead them?
