Mrs Tymoshenko, the Prime Minister, made the appeal on Tuesday, claiming the result was rigged. International monitors deemed the vote free and fair.

The court says the result should be suspended while it considers the evidence she has submitted.

The winner, Viktor Yanukovych, is due to be inaugurated on February 25.

The supreme administrative court ruling concerns the Ukrainian Central Electoral Commission's declaration on Sunday that Mr Yanukovych has won the vote.

The results showed Mr Yanukovych have beaten Mrs Tymoshenko by a margin of 3.48%.

The court is due to rule on Mrs Tymoshenko's appeal to have the results thrown out in the coming days.
