Elections in Kiribati are held every 4 years or, earlier, after a no confidence vote.
Kiribati elects on national level a legislature and then a head of state - the president.
The House of Assembly (Maneaba ni Maungatabu) has 45 members, 44 elected for a four-year term in single-seat and multi-seat constituencies, and 1 delegate from Rabi Island representing Banaba.
Kiribati has an informal party system, and the website of the House of Assembly of Kiribati says the following on the topic:[1] The parties are loose groupings rather than disciplined blocks, with little or no structure.
It is also common for members to vote according to the special interests of their electorate on certain issues.Walsh, Michael Ravell (2020).
