What form of government does the top elected official not propose new laws?

In a parliamentary system, the top elected official, often the prime minister, typically does not propose new laws directly; instead, legislation is usually introduced by members of the parliament. The prime minister leads the executive branch and works with the legislative body to influence policy but does not have the same formal role in lawmaking as in a presidential system. This separation allows for a collaborative approach to governance, where the parliament plays a central role in law creation.
