The president stressed Ukraine should protect and strengthen national unity.

Ukrainian President Petro Poroshenko says Ukraine is a unitary state and there will be no federations and special statuses for individual regions.

"It should be clear for everyone: Ukraine is a unitary state with one state language, as spelled out in the Constitution. No federations and no special statuses. The united, independent Ukraine," he said at Kyiv's St. Sophia Square on Unity Day of Ukraine and the 100th anniversary of the proclamation of the Reunification Act between the Ukrainian People's Republic and the Western Ukrainian People's Republic, an UNIAN correspondent reports.
