"I believe that Yuliia Tymoshenko is mother of Ukraine's economic weakness, destruction of Ukrainian independence, corruption, populism and inefficiency. She's a real [corruption] mother who during long time, 20 years, was doing her utmost to destroy Ukraine. And every time she failed on something, she blamed it on someone else... Yesterday, I heard some of her remarks at a press conference. They were a complete lie. I understand she strives to get to power. It's an end in itself for her," Hroisman said.
