The official Communist Party newspaper Pravda says Soviet leader Mikhail Gorbachev's glasnost policy of openness should be made the law of the land but indicated limits should be placed on how far it could go. "It is a misconception that glasnost and secrecy exclude each other," Pravda, the daily mouthpiece of the Communist Party, said Sunday. "Glasnost, as (tate founder Vladimir) Lenin understood it, means a truthful conversation about essential things." By citing Lenin as an authority, Pravda made plain it was laying down the official line.
