The political party of Ukrainian President Victor Yushchenko has suspended coalition talks with ex-ally Yulia Tymoshenko.
Our Ukraine party officials say at issue is Tymoshenko's recent statement that the post of prime minister should go to her supporters, because Mr. Yushchenko is president.
Senior officials of Mr. Yushchenko's Our Ukraine party have said in the past they will not accept Tymoshenko as prime minister. She was fired from that post last year following infighting in the cabinet.
No party won enough parliamentary seats in the March 26 general election to form a government. The pro-Russian opposition Party of the Regions won 32 percent of the vote, followed by Tymoshenko's liberal bloc with 22 percent. Our Ukraine won about 14 percent.
The new parliament is scheduled to convene on May 25.
