>Interestingly, the PM in a Westminster model is actually more powerful than the President in the US mode. That’s because the PM is part of legislative and executive branch and in theory can get more of their agenda done. In practice, it can vary.
I don't know of any cases among the developed English-speaking countries with Westminster-style governments where your latter sentence is meaningful. The Canadian Prime Minister, especially, is said to be the most powerful single government leader in the world, but really is merely the (to coin a phrase) first among equals among his peers in other countries.
For others' benefit, a Canadian Prime Minister can
* Appoint anyone he wants to cabinet positions
* Appoint anyone he wants to the Supreme Court[1]
* Appoint anyone he wants to ambassadorships and other high positions
* Sign any treaty he wants
* Call an election whenever he thinks he has the best chance of winning more seats than his party possesses in Parliament at the moment
* Get any law passed he wants (assuming that his party has a majority or equivalent thereof), with no meaningful need to deal with an upper house
* Run for reelection as Prime Minister as often as he wants
Most of the above apply to the UK, Australia, New Zealand, and Ireland. The Irish and British upper houses have little power, and New Zealand no longer has an upper house; only Australia has an upper house in the legislature with significant power.
[1] Yes, yes, I know about the convention that the PM names someone from a list of suggestions. That's all that is; a convention. The only actual requirement is that three of the nine justices have to be from Quebec.
