In this photo taken Wednesday, Sept. 12, 2012, Georgia's billionaire and opposition leader Bidzina Ivanishvili speaks during his interview with The Associated Press at his home in Tbilisi, Georgia. Georgia's richest man, multibillionaire and philanthropist Bidzina Ivanishvili is on a collision course for political power with President Mikhail Saakashvili — his onetime close friend and ally. Ivanishvili was an early supporter of Saakashvili after he came to power following the 2003 Rose Revolution demonstrations that drove out the corruption-riddled regime of Eduard Shevardnadze. But Ivanishvili, who made his fortune in Russia, gradually became disenchanted and began to fear that his disagreements with Saakashvili could imperil his future. (AP Photo/Shakh Aivazov)
