Ukrainian Parliament Commissioner for Human Rights Valeria Lutkovska has ruled out releasing jailed former Prime Minister Yulia Tymoshenko for treatment overseas, according to Xinhua.
"To date, there is no legal basis to allow a person who has been convicted in Ukraine to obtain treatment abroad," local media cited Lutkovska as saying.
Tymoshenko, 52, who was convicted in October 2011 of abuse of power over a 2009 gas deal with Russia, has been suffering from severe back pains since her conviction.
The former prime minister has been treated by Ukrainian and German doctors for more than a year at a health center in the eastern Kharkov region.
Tymoshenko claims she needs urgent surgery for serious problems with her spinal column, but has refused further medical treatment in Ukraine.
In June, German Foreign Minister Guido Westerwelle offered to provide Tymoshenko with medical treatment in Berlin.
