Head of Government is an established role in diplomatic speak that can be used across various types of governments to describe the person in control of what the USA would selfdescribe as the Executive Branch, but basically a government’s administration. In parliamentary systems, this role is usually held by the Prime Minister or equivalent.
This is a different role from Head of State, which is typically seen as the public persona of the state in diplomacy.
Some political systems, like the USA’s, combine the roles while others, like UK and China, keep them separate.
The president is the head of one of three branches of the government.
