Ukrainian President Petro Poroshenko has signed a number of laws on combating corruption and smuggling, Deputy Head of the Presidential Administration of Ukraine Andriy Taranov said at a briefing on Wednesday.

According to the president's website, two of the signed laws extend the functions of the National Anti-Corruption Bureau.

The law on amending Article 216 of Criminal Procedural Code on specifying Anti-Corruption Bureau's jurisdiction allows the Anti-Corruption Bureau to check officials' declarations and gives the bureau's detectives the authority to conduct a pre-trial investigation of crimes connected to the declaration of false information.

"Thus, if an official 'forgets' to include something in the declaration, the Anti-Corruption Bureau's detectives will investigate him," Taranov said.

Another law on amending Article 36 of the law on preventing corruption allows the National Anti-Corruption Bureau to thoroughly check declared information.

"Uncompleted construction, a building belonging to declaring person's entourage, a building on declarant's land – all these will be examined," Taranov said.

The law on amending the law on principles of preventing and battling corruption regarding declarants serving in the military is aimed at protecting the rights of mobilized persons and members of their families.

"If a person was drafted for service in 2014 and by April 1 he didn't manage to prepare a declaration because of serving in the military, he can file such a declaration within 30 working days after coming back to work," Taranov said.
