Cabinet department
A cabinet department or prime minister's department is a department or other government agency that directly supports the work of the government's central executive office, usually the cabinet and/or prime minister, rather than specific ministerial portfolios. Such a department is present in many parliamentary democracies. The department is roughly equivalent in function to a president's office in a presidential system of government or an office of the council of ministers in a semi-presidential system.
In many countries, such a department is called a Prime Minister's Office. In some other countries, there is a Cabinet Office. In the United Kingdom, the Prime Minister's Office is a part of the Cabinet Office; in Australia and New Zealand, there is a single department called the Department of the Prime Minister and Cabinet. In some countries, such as Germany and Poland, the department supporting the prime minister is called the chancellery.
Self-governing states and provinces within federations that are parliamentary democracies often have similar departments, such as a premier's department or, in Australia, Department of the Premier and Cabinet.List of cabinet or prime minister's departments
