"Today, Heritage Party addressed a letter to RA President Serzh Sargsyan requesting him to appeal to RA Constitutional Court for the study of preliminary RA-Turkish Protocols," Heritage Parliamentary Faction Leader Stepan Safaryan told a news conference.

According to Safaryan, the letter urges the President to conduct a nationwide referendum on RA -Turkish protocols. He also added that discussions have to start before documents are signed, as there's no point in discussions after they're concluded.
