KIEV, December 19 - RAPSI. The Ukrainian Prosecutor General's Office plans to question former Prime Minister Yulia Tymoshenko as part of the investigation into MP Yevgeny Shcherban's murder as soon as her health improves, First Deputy Prosecutor General Renat Kuzmin said on Wednesday.

"Several medical conclusions have been issued that recommend investigators not to communicate with Tymoshenko," the UNIAN news agency quoted Kuzmin as saying. "As soon as we receive permission, then we will begin to work with Tymoshenko."

Shcherban, who was an MP and also the head of the Anton financial corporation, was shot dead at the Donetsk airport in November 1996. His wife and an airport employee were also killed.

Shcherban's son Ruslan reported in early April that he had submitted documents to the investigators regarding Tymoshenko's alleged involvement in his father's murder. She is presently a witness in the Shcherban case, but according to Kuzmin, the office has sufficient grounds to bring charges against her.

In October 2011, Tymoshenko was sentenced to seven years in prison for abuse of power based on a 2009 gas contract that she signed with Russia. She is serving her sentence in a Kharkiv women's prison. She has been receiving treatment at a local hospital since May 2012. She was diagnosed with a spinal disc herniation.

In late March, a second case bringing further charges against Tymoshenko was filed with Kharkiv's Kievsky District Court. The case deals with her activity at United Energy Systems. She has also been accused of misappropriating funds.
