Ukrainian President Petro Poroshenko has said his country will implement reforms despite the opposition from bureaucracy, oligarchs and anti-Ukrainian forces.

"Together, we will succeed in everything, despite the Russian aggression, despite the mistakes we make, despite the subjective and objective difficulties, despite the efforts by the anti-reformist Fronde that is being formed before our very eyes by corrupt bureaucracy, oligarchy, the underworld and the fifth column," Poroshenko told graduates at the National University of "Kyiv-Mohyla Academy" on Friday.
