Ukraine's former prime minister and leader of the Batkivschyna party Yulia Tymoshenko said she is prepared to restart work, Interfax-Ukraine reports.

"I am returning to work right now. I will not lose a single minute in my effort to allow all in my homeland to feel happy," she said on Independence Square in central Kyiv on Saturday evening after arriving from Kharkiv where she had been serving her term.

"I want to tell you that I will be the guarantor for you, so no one will betray you again, and no one will step on the path the politicians usually walk," she said.

Tymoshenko was sitting in a wheelchair as she was addressing the Maidan audience.

She failed to immediately establish contact with the audience, and her opening words drowned in the audience's chants: "Heroes Don't Die!"

Her call to bring President Viktor Yanukovych to account caused a wave of approval.

In the middle of the speech she was interrupted by the chants: "We don't trust you!", which were not supported, however.

But her statements about politicians were welcomed with applause.

After Tymoshenko finished her speech people started leaving the square.

To recall, Ukrainian Parliament has passed a bill that allows release of former Prime Minister of Ukraine Yulia Tymoshenko, jailed in 2011 for abuse of power.
