Ukraine's parliamentary life has been in limbo since elections on March 26 failed to produce a clear winner and negotiations on forming a coalition between the Yulia Tymoshenko Bloc, Our Ukraine and the Socialist Party have been complicated over disagreements on who should be appointed prime minister.
But Our Ukraine's Roman Zvarych said that only a few positions needed to be coordinated.
"The working group has 95% completed work on the draft coalition agreement as part of the negotiating process on establishing the coalition," he said.
Parliament officially opened May 25, but has been hamstrung by the lack of a coalition, as the wrangling over the prime minister's chair - Tymoshenko is looking to serve in her second stint as premier - and policy differences over Europe and NATO membership have prevented the three would-be members from signing a final document.
Zvarych highlighted these divergences over Ukraine's role in the world.
"In particular, these are the rates and procedure for Ukraine's integration into Euro-Atlantic organizations, in other words, Ukraine's accession to NATO," he said. "But the Socialists reject this position."
President Viktor Yushchenko previously said a coalition agreement had to be signed before the first session of parliament. If parliamentarians fail to strike an agreement a month after the parliament starts work, the president is entitled to disband the legislature and call new elections.
