KIEV, Jan. 25 – The main precondition for the adoption of amendments to the Constitution of Ukraine in terms of decentralization should be the establishment of a complete ceasefire in Donbas, President Petro Poroshenko said.

"I welcome the initiative of 53 MPs, because voting for the Constitution in terms of decentralization should be preceded by a number of important preconditions. The first one is the ceasefire and a long period of silence. This should be ensured by Russia and the world needs to see this happening," the president said in an interview with Ukrainian TV channels broadcast on Sunday evening.
