Gorbachev's policy (8)
I believe the answer is:
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">gorbachev's policy</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for glasnost that I've seen before include "Gorbachev's policy from 1985" , "Gorbachev's policy of "openness"" , "Soviet policy of openness" , "Gorbachev initiative" , "Openness (Russian)" .)
