Input: Question: By what Margin did Pascal Lissouba win the August 1993 presidential election? Passage:The Union for Democratic Renewal (Union pour la Renouveau Démocratique) was a coalition of political parties in the Republic of the Congo. The coalition was led by Bernard Kolélas, who was also the leader of the coalition's largest party, the Congolese Movement for Democracy and Integral Development (MCDDI). The URD parties supported the transitional government of Prime Minister André Milongo (1991–1992) and opposed the National Alliance for Democracy (AND), which included the Pan-African Union for Social Democracy (UPADS) and the Congolese Labour Party (PCT). In the parliamentary election held in June–July 1992, the AND parties won a slight majority of seats in the National Assembly and UPADS leader Pascal Lissouba was victorious over Kolélas in the August 1992 presidential election.
