At present, three sovereign monarchies are members of the African Union: Eswatini (ruled by King Mswati III, with Ntombi), Lesotho (ruled by King Letsie III), and Morocco (ruled by King Mohammed VI of Morocco). Lesotho is a constitutional monarchy, in which the king or queen serves a largely ceremonial function; he no longer possesses any executive authority and is proscribed from actively participating in political initiatives. According to the constitution, the leader of the majority party in the assembly automatically becomes prime minister; the monarch is hereditary, but, under the terms of the constitution which came into effect after the March 1993 election, the monarch is a "living symbol of national unity" with no executive or legislative powers; under traditional law the college of chiefs has the power to determine who is next in the line of succession, who shall serve as regent in the event that the successor is not of mature age, and may even depose the monarch. Eswatini (Swaziland) is an absolute monarchy, currently in the process of democratization. According to current Swazi law and custom, the monarch holds supreme executive, legislative, and judicial powers. The king ("Ngwenyama") is a hereditary leader, receiving assistance from a council of ministers and a national legislature. The senior queen ("Ndlovukati") is in charge of national rituals, and acts as regent if her counterpart Ngwenyama dies and the heir has not performed royal adulthood rituals or is indisposed. If the king's mother is no longer living, one of the king's wives may act as Ndlovukati. The king has constitutional protection from arrest and trial.
