Citizens here are aware the the leader of the political party gets the PM post. And the leader has to stand for elections in an SMC or GRC. If voters reject the leader of the party, the leader will cease to be their leader when his other political comrades gets elected while he or he and his team doesn't get elected.
Bro.
You can just straight forward said that citizen does not have the power directly vote for a PM.
The cabinet majority party will choose their leader/PM.
It can be anyone in the party elected MP but does not means he/she can be a successful PM.
