Even though Yushchenko's party, Our Ukraine, worked with the rival bloc controlled by Prime Minister Yulia Tymoshenko to pass legislation dealing with the global financial crisis recently, Yushchenko said Monday the former coalition between the two can't be repaired, RIA Novosti reported.
"In this situation, snap elections are the only constitutional way out," Yushchenko said.
His partnership with Tymoshenko collapsed this year when she supported a move to reduce the president's powers and sided with pro-Russian parliamentarians in opposing Russia's military actions against Georgia.
Yushchenko said Tymoshenko had acted dishonestly by conducting secret negotiations against him.
"Approval of the anti-recessionary bill can in no way be considered a sign that the ability of the Supreme Rada (parliament) to work has been restored," Andrey Kislinskiy, deputy head of Ukraine's presidential secretariat, said in the RIA Novosti report.
