The former Soviet state is facing snap parliamentary elections after the pro-Western alliance failed to reach a deal on a new coalition in September, when lawmakers from the pro-Russian opposition, the Party of Regions and the Communist Party, backed by Prime Minister Yulia Tymoshenko's bloc, voted to reduce presidential powers and simplify impeachment procedures.
"I am giving a chance until October 7 to all those who committed adultery and those who remained faithful to communicate as responsible politicians and offer society a way out of the deadlock," Yushchenko said, adding that he currently had the right to dissolve the Supreme Rada.
The president said he was pinning little hope on the coming snap elections, comparing the annual polls to "Mexican TV series" and urging "conciliation around national priorities."
Ukraine held parliamentary polls in March 2006 and September 2007.
Yushchenko also said he would accept any coalition.
"If any coalition is formed, I will bow my head and say 'I will put forward a candidacy of prime minister from the new coalition,'" he said.
The Ukrainian leader also urged the Tymoshenko bloc, the Party of Regions and the Communists to formalize their relations and inform the community of agreements they might reach.
President Yushchenko refused Friday to give former parliamentary speaker Volodymyr Lytvyn's bloc the right to be part of the democratic coalition.
