Gorbachev's 1985 slogan involving more open government (8)
I believe the answer is:
glasnost
(Other definitions for glasnost that I've seen before include "Policy of openness under Gorbachev" , "Gorbachev's policy from 1985" , "Gorbachev's policy of "openness"" , "Openness (Russian)" , "Gorbachev initiative" .)
