Final answer:
The executive branch of government includes the Prime Minister (PM), Premier, and their cabinets. This branch enforces laws and includes the leadership of governmental ministries or departments.
Step-by-step explanation:
The branch of government that includes the Prime Minister (PM), Premier, and their cabinets is the executive branch. In most democracies, there are primarily three branches of government: the legislative, executive, and judicial branches.
Specifically, in a parliamentary system, there is a close relationship between the legislative and executive branches. The head of the executive branch is often the prime minister, who is also a member of the legislative authority. In contrast, a presidential system features a stronger separation of powers, and the president has only a limited role in legislative processes.
