As a former British colony, Fiji has largely adopted British political models and follows the Westminster, or Cabinet, system of government, in which the executive branch of government is responsible to the legislature.

Under the 2013 Constitution, the prime minister is the leader of the political party which has won more than half of the total number of seats in Parliament.

If no such party exist, the Parliament elects the prime minister.

Mara's first term as prime minister lasted until 13 April 1987.

He returned to the office for the second term on 5 December 1987, serving until 2 June 1992.
