KIEV — When Ukraine's president opened up his home to TV cameras, he presented a cozy place with a small office just big enough for his grandchildren to play in. But his critics point to strong evidence he actually lives in very different digs: a luxurious, marble-columned mansion with a golf course, a helipad and even an ostrich enclosure. The reported grandeur is becoming a campaign issue in a country quickly getting fed up with widespread corruption. Critics call Viktor Yanukovych's home an emblem of the secrecy and arrogance that defines his presidency, painting him as a leader who basks in splendor while his main political opponent, former Prime Minister Yulia Tymoshenko, is locked up in prison on charges the West has called politically motivated. Yanukovych has refused to answer questions about the house or the vast park where it sits, once darkly suggesting that an investigative journalist back off. An opposition activist looking for answers broke into the property James Bond-style, scaling the walls with a tow rope. She was detained, but still managed to salvage photographs of a golf course and glitzy buildings, describing an opulent palace guarded by heavy security. Political commentator Vitaly Portnikov, who has compared Yanukovych's government to a “mafia” jeopardizing Ukraine's desire for greater integration with the European Union, cited Yanukovych's clandestine residence as an example of the corruption and lack of transparency unacceptable in the West. “Viktor Yanukovych's main goal is not to be the president of Ukraine but to be the No. 1 oligarch in Ukraine,” said Portnikov. “He fought for power ... specifically in order to consolidate in his hands a huge amount of resources and property, in order to make his family the first family in the country.” The two main opposition parties are likely to gain ground in Sunday's parliamentary election. But with the pro-Western opposition's charismatic leader in jail and a lack of unity among government critics, the president's Party of Regions is expected to retain its majority in parliament. Yanukovych, who returned to power in 2010 after a period out of office, maintains a strong core of support, especially in the Russian-leaning east and south of the country, claiming credit for bringing stability after years of paralyzing political infighting and economic free-fall. Yanukovych's home is in Mezhygirya park, 345 acre of forested hills situated along the Dnipro River, some 25 km north of Kiev, the capital. Founded decades ago on the ashes of an Orthodox Christian monastery, the park included a government residence for top Communist Party bosses like Soviet leader Nikita Khrushchev, and is off limits to the public. Through a series of controversial government acts, Yanukovych was able to privatize a modest house on a 4.4-acre plot of land inside the park. After that, two firms were allowed to lease the park from the government for 49 years. They demolished most of the Soviet-era buildings, including the government residence, and began construction of new houses and sports clubs. Yanukovych has refused to say who is behind the two firms, but his critics have no doubts. Mezhygirya is “a symbol of the president's inappropriate desire for luxury, the unknown source of his wealth and the desire to hide it all behind dummy firms,” said Serhiy Leshchenko, a journalist with the Ukrainska Pravda news site whose investigation has linked the two firms to Yanukovych and his family. Seeking to counter criticism, Yanukovych invited six trusted journalists to Mezhygirya in the summer of 2011 and gave them a tour of his official house. He led the men into his bedroom, where an Orthodox Christian icon stood on a bedside table, and then his small office, where he lets his grandchildren play while he works. He also showed them a fireplace in the living room he said he had to abandon because a family of owls had settled inside. But ownership documents for the two firms uncovered by Leshchenko link them to Yanukovych and his allies and bolster claims that he controls the entire estate. Aerial photos taken by the Korrespondent weekly magazine show that the property appears to be one entity, complete with a giant mansion, fruit and vegetable greenhouses and an array of sports facilities. Journalists who have tried to get into the park or even a nearby village have been stopped by government security agents. — AP
