BRUSSEL, September 28 - RAPSI. The European Commission is seriously concerned with former Ukrainian Prime Minister Yulia Tymoshenko's possible sentence and called upon the Ukrainian authorities to prevent selective justice, European Commission representative Maya Kosjancic said on Wednesday.

"We emphasize the need for transparent investigations, prosecutions and court trials," she told journalists in Brussels.

Tymoshenko's attorney said the court might pass its judgment next week. Meanwhile, Yuri Sukhov, another attorney of the former prime minister, told Tymoshenko's official website that the sentence might be passed by the end of the week.

The Prosecutor General's Office charged Tymoshenko with abuse of power in connection with her approval of a Russian gas contract in 2009 when she was a prime minister. She was arrested on August 5.

The state prosecutor demanded seven years in prison for Tymoshenko on Tuesday.
