What's Wrong with This Picture? Part II

Moscow's longtime mayor, Yuri Luzhkov, in office since June 1992, was fired on 28 Septemeber.  The unstated but obvious reason is that there was a power struggle between him and Russia's president, Mr. Medvedev.  In the campaign to unseat Mr. Luzhkov, a string of stinging news shows showed or implied significant corruption by Mr. Luzhkov and his wealthy wife, Yelena Baturina.

Mrs. Baturina's wealth was coincidental with her husband's tenure as mayor of Moscow.  This is obvious to Russians and a common subject of satirical remarks in daily conversations.  But only when her husband, Mr. Luzhkov needs to be sacked - and not a moment before - allegations of corruption arise.
