Slogans revised on time for social policy (8)
I believe the answer is:
glasnost
'social policy' is the definition.
(I know that glasnost is a type of social policy)
'slogans revised on time' is the wordplay.
'revised' indicates an anagram.
'on' says to put letters next to each other.
'time' becomes 't' (abbreviation).
'slogans' is an anagram of 'glasnos'.
'glasnos'+'t'='GLASNOST'
'for' is the link.
(Other definitions for glasnost that I've seen before include "Gorbachev initiative" , "Gorbachev's policy of "openness"" , "Policy of openness under Gorbachev" , "Openness (Russian)" , "Soviet policy of openness" .)
