Ukraine's parliament (Verkhovna Rada) decided to hold the country's presidential election on October 25.

President Viktor Yushchenko said he would challenge the 'unconstitutional' decision in the Constitutional Court.

In a voting Wednesday, the resolution received an overwhelming support of 401 deputies, when 226 votes were enough for it to pass through.

The parliament's decision was based on an amendment to the Ukrainian Constitution in 2004, which stipulated a five-year term for the president. It came into force January 1, 2006, after the election of Yushchenko.

The president's secretary, Marina Stavniychuk told a news conference that Yushchenko was appealing the parliament's decision, as he believed that the regular presidential election should be held on January 17, next year.
