Prime Ministers in some countries are appointed by the monarch.

In countries with a constitutional monarchy, such as the United Kingdom, the prime minister is appointed by the monarch and is typically the leader of the political party that has the most seats in the parliament. While the monarch technically has the power to appoint the prime minister, in practice, the appointment is a formality as the choice is usually based on the election results. This system of appointment helps maintain a balance between the monarch's ceremonial role and the government's democratic functions.
