KIEV, Oct. 21 ??“ Viktor Yushchenko takes on a defining moment for his presidency Monday, when his government auctions off a 93.02% stake in Kryvorizhstal, the steel company which accounts for about 20% of Ukraine??™s steel production.

The steelmaker was originally sold last year in an apparently rigged auction to a consortium backed by two of Ukraine's richest men, Rinat Akhmetov and Viktor Pinchuk, the son-in-law of then-president Leonid Kuchma. It was the widespread perception of the unfairness of this first attempt at Kryvorizhstal privatization that helped fuel the anti-corruption drive that catapulted Yushchenko and his erstwhile ally, Yulia Tymoshenko, to power as part of the so-called Orange Revolution.
