2.5 - Removal of Executives
Legislatures can remove executive leaders through various procedures meant to control the abuse of power, but the specific mechanisms and how well they actually work vary a lot across political systems and regime types.
Parliamentary Systems: Vote of No Confidence
Parliamentary systems remove executives through votes of no confidence, a relatively straightforward process compared to impeachment. In the UK, the House of Commons votes on whether it still has confidence in the government, and a simple majority is enough to defeat it, forcing resignation and possibly triggering new elections. This is easier than impeachment, can happen over policy disagreements rather than just misconduct, and removes the entire government collectively, not just the Prime Minister. Confidence votes can be triggered by an opposition motion, a government declaring a vote a confidence matter, a defeated budget, or losing on a major policy.
In 1979, James Callaghan's Labour government lost a confidence vote by a single vote (311 to 310), forcing an election that brought Margaret Thatcher's Conservatives to power. Still, a no confidence vote requires a parliamentary majority willing to bring the government down, which often means the government's own party has to abandon it, so UK prime ministers with a majority are usually pushed out by their own party instead. Boris Johnson survived a Conservative Party confidence vote in June 2022, but in July dozens of ministers resigned and he announced he would step down. His government actually won a formal Commons confidence vote on July 18, 2022 (349 to 238), since the Conservatives still held a majority, and he left office that September once the party chose Liz Truss. Keir Starmer's exit followed the same pattern: he announced his resignation in June 2026 after losing the support of many Labour MPs, not because the Commons voted him out.
Presidential Systems: Impeachment
Presidential systems require impeachment, a formal process for charging executives with serious violations and removing them through quasi-judicial proceedings, deliberately designed to be difficult.
In Mexico, the Chamber of Deputies brings charges and the Senate conducts the trial and votes on removal, requiring a supermajority for conviction, and it applies to the president, cabinet, and other high officials. No Mexican president has ever been successfully removed this way, since the political bar is extremely high, especially when the president's party or coalition holds significant legislative representation.
In Nigeria, at least one-third of the members of the National Assembly must sign a notice accusing the president of gross misconduct. Then two-thirds of all members of each chamber must vote to investigate, the Chief Justice of Nigeria appoints a seven-person panel to examine the charges, and if the panel finds them proven, two-thirds of each chamber must vote again to remove the president. No Nigerian president has been impeached under the Fourth Republic since 1999. In 2012, the House of Representatives threatened to impeach President Goodluck Jonathan over poor implementation of the budget, but the threat never went anywhere, since the high threshold makes removal extremely difficult, though state governors have faced impeachment more often, sometimes for political rather than genuine accountability reasons.
Overall, presidential impeachment tends to work more as a deterrent and political pressure tactic than as a realistic removal mechanism, since fixed terms protect presidents unless there's overwhelming consensus about serious violations.
Semi-Presidential Systems: Impeachment of the President
Semi-presidential systems typically use impeachment for presidents while prime ministers face parliamentary confidence votes instead.
In Russia, the State Duma brings charges with a two-thirds vote, the Federation Council then holds a trial requiring another two-thirds vote, and the Constitutional Court and Supreme Court have to be involved too, an extremely high procedural bar. It exists constitutionally but has never actually been used successfully. In 1999, the Duma tried to impeach President Boris Yeltsin on five charges, including starting the Chechen War, but all charges failed to reach the required 300 votes, showing just how impractical impeachment is when the president has legislative support. Under Putin, United Russia's dominance makes presidential impeachment essentially impossible.
As for the Russian Prime Minister, the Duma can vote no confidence, but if the president ignores the first vote, a second one within three months forces the president to either dismiss the PM or dissolve the Duma. In practice, the president effectively controls whether the PM stays, since the Duma risks dissolution if it keeps pushing. When Putin wants a new prime minister, like swapping Medvedev for Mishustin in 2020, he simply directs the resignation, making the formal Duma mechanisms largely irrelevant.
Authoritarian Systems: Limited or No Removal
Authoritarian regimes either lack meaningful removal mechanisms or design them to be functionally impossible to use.
In China, the National People's Congress could theoretically remove the president, and party structures could theoretically remove the General Secretary, but in reality the Communist Party controls the NPC completely, so leadership changes happen through internal party processes rather than legal procedure. No Chinese leader has ever been removed through NPC action; when leaders fall, it happens through party power struggles behind closed doors, and the NPC just rubber-stamps the outcome. Xi Jinping's consolidation of power has made even informal removal through party elite consensus increasingly unlikely.
In Iran, the Supreme Leader is theoretically removable by the Assembly of Experts if he becomes unable to do the job or no longer meets its qualifications, but this has never happened, and the Guardian Council vets the Assembly's candidates, so it's made up of regime loyalists who would never challenge him. Ali Khamenei served from 1989 until his death in February 2026 without any serious removal threat. The president, on the other hand, can be removed in two ways: the Majles can impeach him (one-third of members start the motion and two-thirds must vote that he's unfit), or the Supreme Court can find he violated his legal duties, and in both cases the Supreme Leader makes the final decision to dismiss him. This has happened once: in June 1981 the Majles impeached Abolhassan Banisadr, Iran's first president, and Ayatollah Khomeini removed him. Majles pressure has also constrained presidents like Mahmoud Ahmadinejad, who in 2012 became the first president summoned to answer questions before the Majles.
Comparing Ease of Removal
From easiest to hardest: the UK (simple majority no confidence vote), Iran's president (parliamentary impeachment with Supreme Leader approval), Mexico and Nigeria (presidential impeachment requiring supermajorities but theoretically possible), Russia (impeachment theoretically exists but is practically impossible given legislative dominance), China (no functional removal mechanism at all), and Iran's Supreme Leader (theoretically removable but effectively permanent).
Parliamentary systems like the UK make removal easiest, since governments serve at parliament's pleasure. Presidential systems like Mexico and Nigeria require impeachment with high thresholds, making removal rare. Semi-presidential systems like Russia theoretically have mechanisms, but presidential dominance renders them non-functional. Authoritarian systems like China and Iran lack meaningful removal mechanisms altogether, concentrating power without real checks.
All systems claim their removal procedures prevent executive overreach, but effectiveness varies enormously. Democratic systems have genuine, if hard to use, mechanisms; hybrid regimes have theoretical procedures that don't actually function; and authoritarian systems lack real checks entirely. Just having removal procedures on paper doesn't guarantee they actually constrain executive power in practice.
