The National Security and Defense Council (NSDC) will consider a concept of the Ukrainian Security Service's (SBU) reform to NATO standards, Ukrainian President Petro Poroshenko has said.

"The National Security and Defense Council will soon consider a concept of the SBU's reform based on the best available practices of NATO member countries," Poroshenko said at the special operations center in Kyiv region on Friday, during celebrations of the 25th anniversary of the SBU.

According to the president, certain functions of the SBU uncharacteristic of a classic security service will eventually be reassigned to other law enforcement agencies.

For instance, the National Anti-Corruption Bureau, the National Bureau of Investigation, and the National Police will investigate certain types of abuse of office and offenses committed by criminal organizations.

The SBU will remain the principal counterintelligence agency of Ukraine, Poroshenko said.
