|Prime Minister of the Imperial Senate of the Esmeraldan Empire|
|Oral Address||The Right Honourable|
|First Holder||Senator Henry Cullen|
The Prime Minister is the title for the leader of the Imperial Senate of the Esmeraldan Empire. The position is appointed by the Imperial Chancellor based on appointee's ability to command confidence in the Senate. This individual is typically a sitting Senator and the leader of the political party or coalition of parties that holds the largest number of seats in that chamber.
The incumbent Prime Minister is guaranteed a seat in the Consilium, although in this particular case it is not required that they are a member of the Nobility as well. The Prime Minister and the Ministers of the Crown are collectively accountable for their policies and actions to the Emperor, to the senate, to their political party and ultimately to the electorate.
