KIEV, October 10 - RAPSI. Former Ukrainian Prime Minister Yulia Tymoshenko's defense complained about the level of uncertainty as to when her sentence will be passed, Tymoshenko's lawyer Mykola Siry told journalists on Monday.

The passing of the sentence may be postponed, he said.

The Ukrainian Prosecutor General's Office charged Tymoshenko with abuse of power in connection with her approval of a Russian gas contract in 2009, when she served as prime minister. Tymoshenko was arrested on August 5. The state prosecution demanded that the former prime minister be sentenced to seven years in prison.

The sentence is slated to be passed on October 11.

Siry believes that the sentence's reading might last three or four hours.
