MOSCOW, July 8 (RIA Novosti) - Political crisis in Ukraine shows that young democracies must tread a fine line when forming coalition majority governments, the speaker of Russia's lower house of parliament said Saturday.

The Ukrainian parliament has been locked in talks on a coalition government for more than three months now. Our Ukraine's coalition with the liberal Yulia Tymoshenko bloc and the Socialists collapsed Thursday over the surprise election of Socialist Oleksandr Moroz as parliamentary speaker. President Yushchenko then called for another coalition to be formed so that he would not have to dissolve the assembly.

"The instability of the parliamentary coalition in Ukraine shows that young democracies should develop a cautious approach toward forming party- or coalition-based governments," Boris Gryzlov told a news conference at the State Duma.

He said that prolonged political crises have a negative impact on the economic and social development of democratic states and each country should develop its own model of democracy, rather that follow pre-set standards.

"The example of Ukraine shows that each country should choose forms of democracy that are most adequate for it, rather than follow patterns that are far away from reality," the State Duma speaker said, adding that Russia, in his opinion, had successfully created a political model that drives the country toward stability.

On Friday, Ukraine's pro-Russian Party of Regions, which won the largest number of votes in a March election, but not enough to form a government on its own, teamed up with the Communist Party and the Socialists to form a new parliamentary coalition and had its leader nominated as prime minister.

If his candidacy is approved by President Viktor Yushchenko, Viktor Yanukovych will become Ukraine's next prime minister.
