TOKYO Ousted Peruvian president Alberto Fujimori has categorically rejected claims that he has 18 million dollars stashed away in secret bank accounts. The allegations of corruption linked to his fugitive ex-spy chief, Vladimiro Montesinos, attracted worldwide media coverage in September when Fujimori's controversial third presidential term was plunged into crisis. "Incredibly, however, no one to this day has been able to present a shred of proof that these accounts exist," AFP reported Fujimori as writing in the third of a four-part series of articles in Japan's Yomiuri Shimbun published Friday. "In fact, Swiss authorities have done away with the notion that there are secret accounts under the name of Fujimori or the Fujimori family," the fallen Peruvian leader said. New Peruvian Prime Minister Javier Perez de Cuellar, a former UN secretary general, had said there was "no evidence" Fujimori had money in Japanese banks or anywhere else, the former president said. "Perhaps the intention has been simply to build an image of a corrupt dictator as an accomplice of Montesinos so as to destroy me politically. "But evidently, these 18 million dollars are not real but imaginary -- counterfeits issued by political hatred and retaliation, or by the network of Montesinos himself." The opposition now holding power in Peru was trying to justify its takeover, Fujimori wrote in Japan's biggest-selling daily. "This political class has been embarrassed by a Peruvian president's being forced to resign outside his country by political persecution and threats to his life, and thus needs to sow seeds of doubt about his honorability." Fujimori has been in Tokyo since November 17, when he stopped over after an Asia-Pacific summit in Brunei. He E-mailed his resignation, but Peru's Congress refused to accept it and chose to sack him for "moral incapacity." After his victory in a controversial May election, Fujimori was engulfed in crisis in September when a leaked videotape showed Montesinos handing over a 15,000-dollar bribe to an opposition member to defect to the ruling ranks. Montesinos, who is now on the run, is wanted in Peru on charges of blackmail, extortion, money laundering and drug trafficking. Swiss Bank authorities have frozen his accounts worth some 70 million dollars. Fujimori, the son of Japanese immigrants, has been urged to return and face questioning over his former spy boss. But he is now safely ensconced in Tokyo after being granted Japanese nationality this month. The former president denied rumors he received one million dollars from a Colombian drug cartel for his 1990 election campaign, or that he had made a fortune by selling shares in Singapore on his way to Tokyo. According to another rumor cited by Fujimori, he flew planeloads of cash on two Hercules Air Force transporters from Peru to Malaysia. "What imagination!" Fujimori protested.
