European Union foreign policy chief Javier Solana is returning to Kiev on Monday for another mediation effort in Ukraine's political crisis, his office said. Solana will meet political leaders along with Polish President Aleksander Kwasniewski, Lithuanian President Valdas Adamkus and Russian envoy Boris Gryzlov. The announcement came after outgoing President Leonid Kuchma rejected reforms to the country's flawed election laws as demanded by the opposition ahead of a re-run of a rigged presidential election due on Dec. 26.
