Even if the incumbent holder of the office wanted to remain prime minister he/she could not do so once the majority of elected parliamentary representatives withdraw their support in favour of someone else.Р”Р„lso, if the majority of Members of Parliament from the governing and Opposition parties express, by a vote, a lack of confidence in the prime minister, he/she could not remain in office. The party's representatives must win the majority of electoral areas or constituencies in order for the party's leader to become prime minister and to form a Government.Р”Р‡urther, if in the course of its governing a country, the ruling party, within its own system, chooses a new leader who is a Member of Parliament, that new leader becomes the prime minister. But, while the appeal of a leader of a political party could be a deciding factor in whether a party wins an election or not, that leader's election alone does not deliver a Government or the prime ministership. Partly responsible for this is that, increasingly, election campaigns highlight the party leader as if he/she is running for office independently of the political party. The debate arises from the view that longevity in office leads to abuse and to the suppression of challengers, both within political parties specifically, and the political system more generally. A debate has now started in parts of the Caribbean about whether there should be term limits for prime ministers.
