What is an executive in a parliamentary government typically required to do to remain in power?

In a parliamentary government, the executive typically requires majority support from the legislature to remain in power. This means that the executive, often led by a prime minister, must be able to command the confidence of the majority of members in the parliament. If the governing party or coalition loses this majority support, it can lead to a vote of no confidence, resulting in the dissolution of the government or the call for new elections. This system emphasizes the importance of being able to maintain stable, majority backing in the legislature, as it directly impacts the legitimacy and functionality of the executive branch.

Maintaining popular support is important but is not a direct requirement for remaining in power in the parliamentary context; rather, it influences electoral success. Similarly, while managing the economy and following judicial decisions are essential aspects of governance, they do not directly relate to the necessity of securing majority support within the parliamentary framework. The core mechanism that ensures an executive's longevity in a parliamentary system hinges on its ability to maintain the confidence of the majority in the legislature.
