KIEV, Dec. 29 (Xinhuanet) -- Ukrainian Prime Minister, presidential candidate Viktor Yanukovych vowed Wednesday not to quit his post.

    "I in principle will not write a statement (of resignation)," Yanukovych said in a press conference in his Kiev campaign headquters.

    He said that the main task of his team is to defend in the Central Election Commission (CEC) and the Supreme Court the choicefor Ukraine "by all legal means."

    Earlier Wednesday, Yanukovych, who came back to work as prime minister from a campaign vacation on Tuesday, was forced to cancela Cabinet meeting after supporters of his rival, opposition leaderViktor Yushchenko, blocked the government building.

    The meeting, however, took place later, but without Yanukovych's participance.

    The CEC has yet to officially declare the results of the Sunday' s reelection, but preliminary results released by the CEC on Tuesday made Yanukovych's rival Yushchenko, the victor with 51.99 percent of the vote against Yanukovych's 44.19 percent.

    Yanukovych has refused to concede defeat and said he will appeal to the Supreme Court in a bid to overturn the result. Enditem
