The exact contents of revised Madrid principles the OSCE MG Co-Chairs will discuss with the Azerbaijani authorities during their visit to Baku are unknown, Orinats Yerkir parliamentary group member Khachik Harutyunyan said.

The parliamentarian voiced hope that revised principles will be made public, as Karabakh conflict settlement issue is gaining transparency. "Afterwards, our party will make a statement, assessing the new principles," he said.
