Ukrainian presidential hopeful Yulia Tymoshenko on Thursday dramatically raised tensions ahead of this weekend's elections  warning of mass street protests if her rival rigged the polls.
 The comments by Tymoshenko  currently prime minister  raised the spectre of a repeat of the 2004 Orange Revolution protests and injected new venom into her cutthroat campaign battle against opposition politician Viktor Yanukovich.
 "If we are unable to guarantee the honest expression of the people's will and honest results  we will mobilise the people. I have no doubt of this " Tymoshenko told reporters at a press conference in Kiev.
 "If he wants falsifications  we are ready to give him such resistance that he has never seen before  not even in 2004 " she added  referring to the Orange Revolution demonstrations that thwarted Yanukovich's last presidential bid.
 "I ask you not to allow Yanukovich to rape our democracy  our election and our country!" Tymoshenko said in an appeal to Ukrainian voters.
 Yanukovich  who is seen as the frontrunner in Sunday's run-off after he beat Tymoshenko by 10 percent in a first-round election in January  dismissed her threat as an act of desperation.
 "This is a sign of her weakness and an indication that she is losing " he told reporters while campaigning in the town of Kryvyi Rig  located in central Ukraine.
 Tymoshenko said the change would pave the way for large-scale vote fraud  but the Regions Party retorted in a statement that her criticism was "hysterical" and "lies."
 Yanukovich is seeking to make a political comeback by beating Tymoshenko in Sunday's run-off election.
 He was initially declared the winner in the 2004 presidential election  but after the Orange Revolution street protests  Ukraine's supreme court threw out the results and ordered a re-run  which Yanukovich lost.
 Yanukovich is generally seen as the pro-Moscow candidate and his strongest support is in the country's Russian-speaking east and south  while Tymoshenko has the most support in more nationalist western and central regions.
 Tymoshenko has cast herself as the champion of democracy and European integration  but has also been criticised as an opportunist who tacks with the political wind.
 He has sought to improve his thuggish image with the help of US political consultants  after being cast as the villain by the Western media during the Orange Revolution.
