I think the way the Westminster system is designed is that the role of Parliament is to hold the government to account for how it is governing and ultimately that accountability is discharged through the electoral process.
I think at the end of the day the way the system is designed to work is that if there is a large disconnect between a Prime Minister and his ministry and their expectations around conduct and those of the general population of parliamentarians, those disconnects play out through the mechanisms that Parliament has to hold a Prime Minister and a ministry politically accountable through question period, appearing before committees, those sorts of things; then, ultimately, for the population it's through an election.
