Answer:
Public policy begins within the executive branch of the political power of a nation, so it is led by the head of government (who can be a president, or a prime minister, or even a group of people).
After the executive agency formulates the public policy, it is carried out by government officials inside government agencies. Sometimes, public policy is itself proposed by government officials, but it has to be approved by the head of government in order to be implemented.
