Kremlin Trains Guns on Luzhkov.

Moscow Mayor Yury Luzhkov has become enemy No.1 for the Kremlin, in a new and hostile stage in the stormy relationship between President Boris Yeltsin and the ambitious mayor. With former Prime Minister Yevgeny Primakov gone from government, likely presidential contender Luzhkov - aside from the Communists - is the only Russian politician who could get between a chosen Kremlin successor and the presidency, political analyst said. And Yeltsin, or his inner circle of advisers dubbed "the family," appears to want him out of the way - to the point of floating a potential election challenge to Luzhkov by former Prime Minister Sergei Kiriyenko in December_s mayoral election. Luzhkov was a main Yeltsin ally in 1993, when the president used tanks to blast the rebellious parliament into submission, and supported Yeltsin_s 1996 reelection. But the relationship between the Kremlin and the mayor_s office cooled sharply, beginning after the August crisis when members of the presidential administration suggested Luzhkov as a candidate for prime minister. They lost, and most of the Luzhkov advocates were purged from the Kremlin.
