Slogans used by the leader of reform in Russia (8)
I believe the answer is:
glasnost
'reform in russia' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.
'slogans used by the leader' is the wordplay.
'used' indicates anagramming the letters.
'by' means one lot of letters go next to another.
'leader' indicates taking the first letters.
The first letter of 'the' is 't'.
'slogans' anagrammed gives 'glasnos'.
'glasnos'+'t'='GLASNOST'
'of' acts as a link.
Can you help me to learn more?
(Other definitions for glasnost that I've seen before include "Gorbachev's policy of "openness"" , "Policy of openness under Gorbachev" , "Openness (Russian)" , "Gorbachev's policy from 1985" , "Soviet policy of openness" .)
