The Executive

The executive branch — the part of government that actually runs things — is organized in two fundamentally different ways.

Presidential Systems

The president is directly elected, serves a fixed term, and cannot be removed by the legislature (except through impeachment for serious offenses). The president is both head of state and head of government.

• Pros: Clear mandate, stability (fixed term), direct accountability to voters
• Cons: Gridlock when president and legislature disagree, winner-take-all, hard to remove a bad president short of impeachment
• Examples: US, Brazil, Mexico, South Korea, Nigeria

Parliamentary Systems

The prime minister is chosen by parliament — usually the leader of the largest party or coalition. They serve as long as they maintain parliamentary confidence. A separate (often ceremonial) head of state exists (monarch or president).

• Pros: Government always has a legislative majority (no gridlock), easier to remove bad leaders (vote of no confidence)
• Cons: Less direct accountability, potentially unstable (Italy has had 70+ governments since 1946)
• Examples: UK, Germany, Canada, India, Japan, Australia

The Cabinet

In both systems, the leader appoints a cabinet of ministers/secretaries who run government departments. Key differences:

• US: Cabinet members serve at the president's pleasure. The Senate must confirm them. They're often outsiders (business leaders, academics).
• UK/parliamentary: Cabinet members are usually sitting MPs. They have more independent power — a rebellion by cabinet ministers can topple a PM.

The Bureaucracy: The Permanent Government

Politicians come and go. The civil service stays. In most countries, career bureaucrats — not political appointees — run government agencies day-to-day.

• UK: Strong tradition of permanent, non-partisan civil service. Ministers set policy; civil servants implement it.
• US: A mix — top agency positions are political appointees (~4,000), but the vast majority of federal employees are career civil servants.
• France: The elite École Nationale d'Administration (ENA) produced presidents, PMs, and top bureaucrats for decades (closed 2022, replaced by INSP).

The quality of the bureaucracy matters enormously. Countries with professional, merit-based civil services (Denmark, Singapore, Japan) consistently outperform those with politicized ones.
