Kyrgyzstan's newly-elected parliament has won the support of key opposition leader Felix Kulov and the central electoral commission.
Mr. Kulov warned that ignoring the results of this month's disputed run-off election could raise the possibility of civil war. But some deputies in the old parliament believe it should retain power.
President Askar Akayev was driven from office amid demonstrations sparked by the election results, which saw the opposition nearly shut out of parliament.
Mr. Kulov was freed from jail by the demonstrators and has helped to restore order to Bishek, the capital, after days of looting and violence.
Constitutional and legal experts from the Organization for Security and Cooperation in Europe are trying to resolve the tensions between the rival parliaments.
Russian President Vladimir Putin said weak leadership, and social and economic problems, contributed to the unrest in Kyrgyzstan. He says he is willing to work with interim leader Kurmanbek Bakiyev.
