"If my victory is confirmed, I am ready to offer the post of prime minister to Viktor Yushchenko," Yanukovich told a press conference, adding he would join hands with his rival to form a joint government and carry out political and constitutional reforms.

Yanukovich, declared the winner of the Nov. 21 presidential run-off, also promised the prime minister's post would be the prime government position after the political reforms.

Yushchenko immediately rejected the offer saying he was unable to accept the proposal, local media reported.

The Supreme Court on Tuesday began a second day of hearings on the presidential crisis.

Yanukovich warned that if the court supported the opposition complaint that the elections in the eastern provinces of Donetsk and Lugansk were fraudulent, his camp would file an appeal to the court on reviewing the elections in western provinces.

If the court rules the elections invalid, Yanukovich declared he will not stand against Yushchenko to avoid a split in the country.

Yanukovich also accused parliament and the Supreme Court of succumbing to the pressure of opposition camp by discussing the issue of dismissing his government.
