"Being aware of the danger of a restoration in Ukraine of a communist-oligarchic government, and with the aim of providing the president with additional constitutional provisions to call for extraordinary parliamentary elections in Ukraine, we state that we are ready to end our terms as members of the Ukrainian parliament," Tymoshenko said.
Tymoshenko today urged deputies from Yushchenko's Our Ukraine party to do the same.
Tymoshenko has repeatedly called on Yushchenko to dissolve parliament to prevent a new "anti-crisis" coalition led by the pro-Russian Party of Regions from forming Ukraine's next government.
The "anti-crisis" coalition was formed after Tymoshenko's party, Our Ukraine, and the Socialists -- the three parties behind Ukraine's 2004 Orange Revolution -- failed to agree on a coalition after inconclusive March elections.
Yushchenko could dissolve parliament after July 25 but he has indicated he has no wish to do so.
