KIEV, January 24 - RAPSI. The criminal case against former Ukrainian Prime Minister Yulia Tymoshenko concerning her activities at the head of the United Energy Systems of Ukraine (UESU) will be brought to the court and the trial will be public, said Ukrainian Deputy Prosecutor General Evgeny Blajivsky on ICTV channel.

The Ukrainian Security Service reported on the completion of a pretrial probe into the UESU case on Friday.

"The investigation will be carried to its conclusion and there will be a public trial," Blajivsky said.

He noted that law enforcement bodies requested a parliamentary approval to hold Tymoshenko liable when she was a people's deputy on three occasions, but such approval was never given.

Blajivsky also stated that investigators see it as a proven fact that Tymoshenko managed the UESU even after 1997, although her supporters insist that she did not.

The investigation has ample evidence to prove its case, he observed.

Tymoshenko was sentenced in October to seven years in prison for abuse of power in signing gas contracts between Ukraine's Naftogaz and Russia's Gazprom in 2009. In late December she was taken to the Kharkiv penal colony. Soon after the sentence was passed the tax police resumed investigation into four criminal cases against Tymoshenko.

The cases bear on her work as head of the United Energy Systems of Ukraine in the 1990s. In the UESU case Tymoshenko has been charged with attempted embezzlement of public funds, organizing a non-disclosure of foreign currency proceeds amounting to more than $165 million, and tax evasion in the amount of over $5.8 million. The Ukrainian Security Service is investigating the cases which were consolidated into one.

The security service closed a criminal case regarding the concealment of currency proceeds on January 18 as the offence has been removed from the Criminal Code. Meanwhile, it will continue investigating Tymoshenko's other crimes.
