Malaysia has a constitutional monarchy system where the Agong is the head of state. The Agong is elected every five years from among the nine Malay state rulers and serves as a largely ceremonial figurehead with limited powers defined by the constitution. These powers include appointing the prime minister, dissolving parliament at the prime minister's request, and conferring honors, with restrictions on ruling their state or leaving the country for long periods. While the Agong has immunity from prosecution for official acts, this was revised in 1992 after an incident to clarify that immunity does not apply to personal conduct.
