Ministry (collective executive)
In constitutional usage in Commonwealth realms, a ministry is a collective body of government ministers led by a head of government, such as a prime minister. It is described by Oxford Dictionaries as "a period of government under one prime minister". Although the term "cabinet" can in some circumstances be a synonym, a ministry can be a broader concept which might include office-holders who do not participate in cabinet meetings. Other titles can include "administration" or "government" to describe similar collectives.
The term is primarily used to describe the successive governments of the United Kingdom, Canada, Australia and New Zealand, which share a common political heritage. In the United Kingdom and Australia a new ministry begins after each election, regardless of whether the prime minister is re-elected, and whether there may have been a minor rearrangement of the ministry. For example, after winning the 1979 general election, Margaret Thatcher formed the first Thatcher ministry. After being re-elected at the 1983 general election, she formed the second Thatcher ministry, and so on. In Canada and New Zealand, a new ministry is only formed if the government loses an election or the succeeding prime minister being from the same party as his or her predecessor.
