With five successive elected civilian governments, the Central American nation of Panama has made notable political and economic progress since the 1989 U.S. military intervention that ousted the regime of General Manuel Noriega from power. Current President Ricardo Martinelli of the center-right Democratic Change (CD) party was elected in May 2009, defeating the ruling center-left Democratic Revolutionary Party (PRD) in a landslide. Martinelli was inaugurated to a five-year term on July 1, 2009.
