Tymoshenko, who was elected premier in December 2007, is the most popular politician in Ukraine. Although she has not yet announced plans to run for president in 2009, analysts say she has been taking advantage of her current position to improve her rating as a potential presidential candidate.
Tymoshenko, who is often criticized for her populist policies aimed at securing maximum support from the electorate, told a parliamentary briefing: "I am not getting ready for the next polls."
The premier said she was seeking a compromise with Ukraine's President Viktor Yushchenko on Constitutional amendments due to be submitted to parliament by her bloc in the future.
"We will attempt to coordinate these amendments with the president," Tymoshenko said.
Tymoshenko is calling for a parliamentary republic to be established in Ukraine, which currently combines features of semi-parliamentary and semi-presidential political systems. The Tymoshenko bloc is seeking to set up a parliamentary constitutional commission for the purpose.
Yushchenko, however, is trying to expand his presidential powers and is opposed to the initiative fearing a commission could become an alternative to the National Constitutional Council, which is also drafting Constitutional amendments.
As tensions increased between the flamboyant premier and Ukrainian leader, the Tymoshenko bloc prevented Yushchenko from making his annual address to parliament on Tuesday.
Yushchenko said the coalition, which includes factions of Tymoshenko's bloc and the pro-presidential Our Ukraine-People's Self-Defense party, "bore full responsibility" for the action and urged the government to focus on curbing inflation instead of indulging in populist measures.
Inflation reached 9.7% in the former Soviet republic in the first three months of 2008.
Tymoshenko has pledged to cut inflation within the next few months.
