 According to Moore, as long as that kind of leadership selection process remains in place and concentrates power in the hands of the leader, as opposed to backbenchers, then coalition governments will be very difficult to form.Moore shows that the diffusion of power within a party tends to also lead to a diffusion of power in the parliament in which that party operates, thereby making coalitions more likely.During the 2008–09 Canadian parliamentary dispute, two of Canada's opposition parties signed an agreement to form what would become the country's second coalition government since Confederation if the minority Conservative government was defeated on a vote of non-confidence, unseating Stephen Harper as Prime Minister.
