The Ukrainian presidential press service said early on Wednesday morning that Poroshenko signed the law at a meeting with representatives of the commission on the election of members of the National Agency for Prevention of Corruption. The document was included in a package of laws required for visa-free travels to the European Union. "The law will take effect in 2016. Officials will file their declarations in 2016 and will bear liability in 2016. I am signing this law in your presence," the president said. All laws and amendments included in the 'visa-free travel package' are important to Ukraine and aim at fighting corruption, the president said. Jan Tombinski, Head of the EU Delegation to Ukraine, who also attended the meeting, welcomed the law and said that European Commission experts had been involved in its elaboration.
