KIEV - The party of President Viktor Yanukovich pushed for a change in the law on Thursday to ease the creation of a new ruling coalition, essential if Ukraine is to dig itself out of economic crisis and avoid elections.

The initiative was condemned as a constitutional coup d'etat by the bloc of Prime Minister Yulia Tymoshenko, ousted in a no confidence vote on Wednesday and who lost a bitterly fought presidential run-off to Yanukovich on February 7.

It appeared aimed at poaching the support of part of the loose Our Ukraine alliance formerly grouped around ex-president Viktor Yushchenko.

Lawmakers of Yanukovich's Regions Party said a coalition and government could be announced next week, after Yanukovich's first official trip to Moscow as president on Friday.

They said former finance minister and close Yanukovich ally Mykola Azarov was the most likely candidate for the post of prime minister.

The proposed amendment would give deputies the right to join a ruling coalition on an individual basis, rather than necessarily as part of a faction as under the current law.

The chaos in the country must be stopped, government resumed. There will be a new coalition and there will be a new cabinet of ministers, said Yanukovich lawmaker Mykhailo Chechetov.

It was unclear whether parliament would vote on the amendment on Thursday and hand Yanukovich a fillip ahead of his talks with the Kremlin.

Parliament dismissed Tymoshenko's government almost a month since Yanukovich's election victory tilted the former Soviet republic back towards Russia.

Tymoshenko, co-architect with Yushchenko of the Orange Revolution of 2004 that brought pro-Western politicians to power, handed the reins of government on Thursday to her first deputy, Oleksander Turchynov.

The Regions Party has 30 days to form a new coalition in parliament or face the possibility of a parliamentary election.

The country of 46 million people -- split between a Russian-leaning south and east and a Western-friendly west and centre -- badly needs strong government to tackle a debilitating economic crisis and restart talks with the International Monetary Fund on a $16.4 billion (10.8 billion pounds) bailout package.

Yanukovich's Regions Party is the largest bloc in parliament with 171 seats, and can count on the support of the Communist faction and the Lytvyn bloc. But such a coalition would still fall short of a 226-seat majority in the 450-seat parliament.

They need the support of at least part of the Our Ukraine bloc, which is divided on the issue. Fifteen of its 71 deputies voted with the Regions Party to dismiss Tymoshenko. Under the current law, to join the coalition a majority of the bloc needs to vote in favour.

Parliament speaker Volodymyr Lytvyn -- leader of the Lytvyn bloc -- said that though there might be certain doubts over the legality of the amendment, he would declare a coalition valid based on the signatures of 226 deputies.

Everyone reads the constitution in their own way, he told Kommersant newspaper. The main thing for me - are there 226 deputies who will take responsibility for decisions in parliament?
