"I'm willing to go, but you have to prove what mistakes we have made," said Kivalov in a talk show in Inter, Ukraine's second biggest private television channel.

Seemingly angered by non-trust motion on the Central Election Commission passed by the Ukrainian congress earlier Saturday afternoon, the top election supervisor said he was preparing to leave, but he could not go like this.

On Saturday afternoon, the Ukrainian congress passed a non-trust motion on the commission, which had overseen the presidential election and later announced on Wednesday that Ukrainian Prime Minister Viktor Yanukovich won the election.

Kivalov requested the law makers of tabling evidences for the errors made by his commission as well as those for the accusations against him and his colleagues.

"We knew a long time ago that we will have become a hostage for the current situation," he said.

Kivalov accused the congress of making the motion "too hastily", saying that the law makers should listen to more comprehensive voice and a special committee should be set up to study the election crisis.

The resolution passed by the congress is not binding with no legal effect.

On Thursday, the Ukrainian Supreme Court ruled that the Ukrainian presidential election result, which was announced by Kivalov's team a day earlier, shall be suspended, leaving a littlebit more time for politicians and international mediators to seek solutions.
