Leader of the Svoboda All-Ukrainian Union Oleh Tiahnybok has said he thinks that the opposition political forces of Ukraine should not unite into a single party.

"I don't think that it is reasonable to create a political force representing different ideologies," he told journalists in Kyiv on Tuesday, while commenting on former Ukrainian Prime Minister Yulia Tymoshenko's statement on the occasion of Unity Day in Ukraine saying that the opposition forces should form a single strong party.

He stressed that the three opposition forces – Batkivschyna, Svoboda, and UDAR – are doing their utmost to resist "the gangster regime of [Ukrainian President Viktor] Yanukovych."

In turn, Leader of the Batkivschyna parliamentary faction Arseniy Yatseniuk said that the creation of a single democratic party was a key task of the opposition.

He said that such a single party should "be able to win parliamentary, as well as presidential elections." He noted that the idea to form a single party was "my and Yulia Tymoshenko's common position, which we declared long ago."

As reported, Yulia Tymoshenko, who was sentenced to seven years in prison for abuse of power, called on the country's opposition forces to establish a united party that would counter the regime of Ukrainian President Viktor Yanukovych.

"The ideal scenario would be further integration processes among opposition forces and the creation of a united party because the steam roller of the Regions Party can be stopped only by a powerful opposition force, which will enjoy unquestionable support in society. A merger of opposition forces and society will accelerate the death of this colossus on feet of clay, in other words the Yanukovych regime," she said in a statement, published on the Batkivschyna Party's Web site.

An Interfax-Ukraine reporter said that on Tuesday the leaders of the oppositional political forces – Arseniy Yatseniuk of Batkivschyna, Oleh Tiahnybok of Svoboda, and Vitali Klitschko of UDAR – laid flowers at the monuments to Ukrainian poet Taras Shevchenko and Ukrainian statesman Mykhailo Hrushevsky in central Kyiv. Around 500 people participated in the event.
