The prime minister of the United Kingdom is the head of government of the United Kingdom. The prime minister advises the sovereign on the exercise of much of the royal prerogative, chairs the Cabinet and selects its ministers. As modern prime ministers hold office by virtue of their ability to command the confidence of the House of Commons, they sit as members of Parliament.
The head of government is either the highest or the second-highest official in the executive branch of a sovereign state, a federated state, or a self-governing colony, autonomous region, or other government who often presides over a cabinet, a group of ministers or secretaries who lead executive departments. In diplomacy, "head of government" is differentiated from "head of state" although in some countries, for example the United States, they are the same person.
Excellency is an honorific style given to certain high-level officers of a sovereign state, officials of an international organization, or members of an aristocracy. Once entitled to the title "Excellency", the holder usually retains the right to that courtesy throughout their lifetime, although in some cases the title is attached to a particular office, and is held only for the duration of that office.
The title chief of staff identifies the leader of a complex organization such as the armed forces, institution, or body of persons and it also may identify a principal staff officer (PSO), who is the coordinator of the supporting staff or a primary aide-de-camp to an important individual, such as a president, or a senior military officer, or leader of a large organization.
