What title is given to the head of a government?

The title given to the head of a government in many parliamentary systems, particularly in the United Kingdom, is Prime Minister. This position entails being the leader of the ruling political party and is responsible for overseeing the operation of the government, making executive decisions, and managing the administration. The Prime Minister represents the country both domestically and internationally, leading the cabinet and being a key figure in establishing government policy.

In contrast, the other titles listed refer to different roles within government structures. For instance, "Chancellor" can refer to a high-ranking official, often in charge of specific portfolios like finance, but is not typically the head of the government. "Secretary of State" usually denotes a senior government official responsible for a specific area, such as foreign affairs, rather than the overall head of government. "Governor," meanwhile, generally refers to the head of a specific region or state and does not apply to the leadership of a national government. Recognizing these distinctions highlights why the Prime Minister is the correct title for the head of a government.
