Context: Most prime ministers in parliamentary systems are not appointed for a specific term in office and in effect may remain in power through a number of elections and parliaments. For example, Margaret Thatcher was only ever appointed prime minister on one occasion, in 1979. She remained continuously in power until 1990, though she used the assembly of each House of Commons after a general election to reshuffle her cabinet.
