The October 20, 1996 presidential, legislative, and mayoral elections also were judged free and fair by international observers and by the groundbreaking national electoral observer group Ética y Transparencia (Ethics and Transparency) despite a number of irregularities, due largely to logistical difficulties and a baroquely complicated electoral law. This time Nicaraguans elected former-Managua Mayor Arnoldo Alemán, leader of the center-right Liberal Alliance, which later consolidated into the Constitutional Liberal Party (PLC). Alemán continued to privatize the economy and promote infrastructure projects such as highways, bridges, and wells, assisted in large part by foreign assistance received after Hurricane Mitch hit Nicaragua in October 1998. His administration was besieged by charges of corruption, resulting in the resignation of several key officials in mid-2000. Alemán himself was subsequently convicted of official corruption and sentenced to twenty years in jail.
