Blue &Yellow: Politics and Economics in Ukraine

According to Reuters, Firtash agreed to reimburse some $2.5 billion to Gazprom and Naftogaz, the Ukraine state gas company. But Timoshenko claims that the gas was worth about $3.5 billion, leaving about $1 billion in profit. She claims that some of that went for mischief against Yanukovich's opposition, including herself. "Since taking power, the Yanukovich administration, aided and abetted by the defendants and other co-conspirators, have launched a wave of arrests and investigations aimed at plaintiff Timoshenko and her political allies in what most objective observers consider to be a concerted campaign to intimidate, suppress and ultimately eliminate any and all political opposition in Ukraine," the suit alleges.

Tymoshenko's lawsuit discussed at Oil and Glory, where one can find more details about the case.  The most interesting part is her allegation that the new administration choose to lose the Stockholm arbitration case.  A good post on the ongoing legal battle between the former prime minister and the current government.
