NATO Secretary General Jens Stoltenberg on Thursday, Oct 31, in his address to the Verkhovna Rada deputies in Ukraine has called on the authorities to reform the country's SBU security service and establish parliamentary oversight over defense and security agencies.

"This newly elected parliament has an historic opportunity to change Ukraine to the better. And you have already made a strong start. I look forward to the implementation of the Law of National Security, passed last year. With parliamentary oversight over the security agencies and defence institutions.  And the reform of the Security Service," Stoltenberg said in his address.

Stoltenberg also said advisers will help "make all aspects of public life open and transparent."
