Normally the leader of the majority party becomes the prime minister, or an office of equivalent function, and selects the other ministers. In the Westminster system, these ministers continue to represent their constituency in parliament while being part of the government. Often, a person from the outside may be appointed minister, usually in order to bring special skills to the government. Such a person would not have to be part of the parliament while serving as minister, nor would he/she necessarily be a member of the party/parties in government.
