Jailed former Ukrainian prime minister Yulia Tymoshenko has been moved back to a prison from a clinic in Kharkov, head of the group in defense of the ex-premier and member of the Ukrainian parliament Serhiy Vlasenko said on Sunday.

“According to our information, yes (she has been moved back to the prison),” Vlasenko said, adding that in his opinion the decision was made because Tymoshenko had been moved to the clinic contrary to her will.

Vlasenko said Tymoshenko had been intentionally misinformed about the conclusions of German doctors who said that her medical treatment in the Kharkov clinic was inadvisable.

Tymoshenko has stated on many occasions she does not trust Ukrainian doctors.

Ukraine’s State Penitentiary Service said on Friday that Tymoshenko had been moved from the prison to a clinic in Kharkov to receive recommended medical treatment.

“Tymoshenko has arrived at the [Kharkov’s Ukrzaliznytsi] clinic where she will undergo a course of treatment recommended by the German and Ukrainian doctors,” the service said in a statement.

Tymoshenko’s health has deteriorated since her pre-trial detention began in August 2011 and she claimed she was no longer able to attend court hearings due to back problems.

A team of German doctors, which examined Tymoshenko earlier in April, has confirmed that the ex-premier is unable to participate in court proceedings.

The jailed politician has repeatedly refused treatment in a penal colony where she is serving her seven-year sentence on charges of abuse of office, for exceeding her authority in signing a 2009 gas deal with Russia.

She has also been charged in a new case with attempting to embezzle $405 million of government funds during the 1990s, when she headed Ukraine’s state corporation United Energy Systems.

Tymoshenko maintains her innocence in both cases.
