[2] Following the Orange Revolution and the 2004 presidential elections in December 2004 Ukrainian parliament adopted significant changes (amendments) to the Constitution of Ukraine by introducing concepts of political coalition, coalition government, imperative mandate as well as transferred some power from the President to the parliament, making Ukraine a parliamentary-presidential democracy.

Table 2 shows the Kyiv International Institute of Sociology (KIIS) poll results for the parties likely to pass the three percent threshold.

Commenting the preliminary results the leader of the Opposition Bloc, Natalia Vitrenko expressed: "On what basis does the CEC show the number of voters as 25 million 250 thousand?

Recent reports in the media have indicated that Ukraine's President has also suggested that if necessary a partial recount of the 26 March ballot should be made.

If significant mistakes were made in the tally of votes there is a chance for Opposition Block of Natalia Vitrenko to exceed the 3% threshold required by law.

According to Arabic newsmedia Al Jazeera, Party of Regions had alleged that the general elections had been marred by irregularities and poor organisation as the first exit polls were published.

The Party of Regions, led by Viktor Yanukovych, who was defeated by Yushchenko in 2004 following massive street protests known as the Orange Revolution, secured a commanding 33.3 percent of the vote, according to one poll.

[11] On 27 March, Arabic Al Jazeera reported that Yulia Tymoshenko, the former PM, had scored a triumph in parliamentary elections with her own bloc coming second and placing her in a position to form a coalition government.

The outcome was a double humiliation for Viktor Yushchenko, the president, who defeated Yanukovich in a presidential poll re-run after December's 2004 street protests, and later fell out with Tymoshenko, his former Orange Revolution comrade.

[12] According to Forbes, Tymoshenko urged her estranged Orange Revolution allies to form a united front against their old pro-Russian nemesis, who was leading in early results from a weekend parliamentary election.

[13] Russian online newspaper Lenta.ru reported that activists of Vitrenko's party erected tents and started boycotting the premises of Ukrainian Central Election Commission in protest of alleged violations.

That led to re-appointment of Viktor Yanukovych as Prime Minister on 4 August, with the backing of 30 deputies of the "Our Ukraine" Bloc, after the parties agreed on the principals of state policy expressed in the Universal of National Unity.
