Panama ? Conservative supermarket magnate Ricardo Martinelli won Panama’s presidential election in a landslide Sunday, promising to guide the country through the world economic crisis and an ambitious expansion of the Panama Canal.

The win by Martinelli, of the opposition Alliance for Change, marked a rare center-right election triumph in a region that has seen a wave of leftist leaders.

Electoral Tribunal President Erasmo Pinilla called Martinelli the “indisputable winner” after preliminary results showed him with 61 percent support and governing party candidate Balbina Herrera with 37 percent. Former President Guillermo Endara was a distant third. The winner was announced with 87 percent of the votes counted.
