How a Prime Minister Is Chosen in a Parliamentary Democracy

In a parliamentary democracy, the Prime Minister is chosen by the elected parliament—specifically, the lower house (e.g., House of Commons, House of Representatives).

Typical Process

1. Citizens elect MPs in a general election.
2. The leader of the party (or coalition) that commands a majority in the lower house is commissioned by the head of state (monarch, president, governor-general) to form government.
3. That leader becomes Prime Minister.

If No Majority (Hung Parliament)

• Negotiations for coalition or confidence-and-supply agreements.
• Head of state may invite the leader most likely to secure confidence.
• If no government forms, new election.

The PM remains in office only while retaining the confidence of the lower house (can be removed by vote of no confidence or party room spill).
