Cabinet department

A cabinet department or '''prime minister's department''' (often called a Prime Minister’s Office or Cabinet Office) is a government body that supports the head of government and facilitates the coordination and operation of the cabinet. Unlike line ministries, it typically does not administer a specific policy portfolio, instead focusing on executive coordination, policy analysis, and administrative support. These bodies are broadly analogous in function to executive offices in presidential and semi-presidential systems, though institutional roles differ. Provided by Wikipedia
