Doctors from the Berlin-based Charite clinic will not come on Monday to Ukrzaliznytsia's Central Clinical Hospital in Kharkov, where former Ukrainian Prime Minister Yulia Tymoshenko is undergoing treatment, as they haven't received official permission, the ex-premier's defense counsel, Serhiy Vlasenko, said.

"The German doctors will not come because they have not received official permission," Vlasenko told Interfax-Ukraine.

The Central Clinical Hospital's officials said they did not know whether the doctors of the Charite clinic would arrive.
