KIEV, Sept. 1 - Whether the presidential bill proposing power-decentralization changes to the Constitution passes a second reading in Parliament will depend on how the situation evolves in eastern Ukraine, President Petro Poroshenko said.

"Today's vote is not final but it will give Ukrainian diplomacy a vast field for maneuver. And the final decision, due at the end of the year when 300 votes are needed, I can reassure you my dear fellow citizens, will depend on how the situation in Donbas evolves in these few months and on how Russia implements the Minsk agreements," Poroshenko said in a televised address on Monday.
