Electronic declaration of assets must start in Ukraine on August 15, and it is inadmissible to postpone it and it is not considered, Ukrainian President Petro Poroshenko has said.

"Corruption should be rooted out, but it is better to prevent it… We need the effective control over income and expenses of officials, judges, prosecutors and all law enforcers… We have a tool for this control. This is electronic declaration of all assets that will be launched from August 15. I say once again: everyone must turn the pockets out before society from August 15 – I do not consider other date and I do not even want to hear about the postponement! I ask not to believe rumors and speculations," Poroshenko said in comments posted on the president's website on Thursday.

He said that imperfectness of the relevant law and obvious incompleteness of software cannot be a ground for the postponement.

"I would not permit any maneuvers here! This is my strong political will as the Ukrainian president. It fully meets the will of people… I personally did much to make it real, and I would not allow anyone to backpedal!" Poroshenko said.

He said that electronic declaration is irreversible and it is "an integral part of all our anti-corruption mechanism."

"Let my words be the countdown until August 15. Our Armed Forces are holding the frontline against external enemy, the Russian aggressor. My order as Supreme Commander-in-Chief is no step back in war against corruption, our key internal enemy," he said.
