The official presidential campaign commenced on October 19, 2009, with nominations opening on October 20 through to November 6. The "unofficial" campaign had already started during the summer of 2009 with tents of Front for Change distributing campaign material for Arseniy Yatsenyuk Front for Changes and large scale and billboards stating "Others make problems. She Works" (in the colors and letter type of Bloc Yulia Tymoshenko), and photos of Sergei Tigipko displayed in most Ukrainian towns and TV-adds of Yulia Tymoshenko and Volodymyr Lytvyn shown on national TV. According to Tymoshenko the "She Works" billboards were paid for by the Fatherland Party, and therefore they were also "social". Party of Regions deputy Andry Paruby officially requested that the prosecutor-general's office investigates the sources of financing of Tymoshenko's advertisements. He suggested that public money might have been used.
