IV. POLITICAL ENVIRONMENT As noted, Lesotho and the United States enjoy warm bilateral relations. The U.S. established an embassy in Maseru shortly after Lesotho's independence from Great Britain in 1966, and has contributed substantially to economic development in Lesotho in the years since then, usually as either the largest or second- largest bilateral donor on an annual basis. After four years of multiparty constitutional government following independence, Lesotho's constitution was suspended in 1970 after the ruling Basotho National Party (BNP) refused to cede power to the rival Basotholand Congress Party (BCP), widely believed to have won elections that year. Under Prime Minister Leabua Jonathan, the BNP governed until a military coup in 1986 brought a Military Council to power under Major General Justin Lekhanya. The military government began a process to draft a new constitution and return Lesotho to democratic rule. The military sent King Moshoeshoe II into exile in 1990; Moshoeshoe's son Letsie was installed as king, but Moshoeshoe returned to Lesotho in 1992 and seeks to regain his throne. The BCP came to power in a landslide encompassing every seat in the new National Assembly, in March 1993 elections. Since early 1994, political stability has eroded as first the army, then the police and prisons services, staged mutinies to demand pay increases. In one April 1994 episode, mutinous soldiers killed Lesotho's deputy prime minister. The BCP government's inability to deal with its mutinous security forces has invited attention and expressions of support for Lesotho's emerging democracy from regional states. Under the constitution, national elections must be held again no later than March 1998. The BNP and BCP remain the principal rival political organizations in Lesotho; earlier differences in political orientation between the two parties has blurred in recent years, as South Africa's transition to majority rule has led to a more pragmatic regional political context.
