State censor imprisoned by Trotsky? (7)
I believe the answer is:
lebanon
'state' is the definition.
(Lebanon is an example)
'censor imprisoned by trotsky?' is the wordplay.
'censor' becomes 'ban' (synonyms).
'imprisoned by' means one lot of letters goes inside another.
'trotsky?' becomes 'Leon' (Russian revolutionary Leon Trotsky).
'ban' inserted into 'leon' is 'LEBANON'.
(Other definitions for lebanon that I've seen before include "Beirut's country" , "Middle East country" , "Country with cedars" , "E. Mediterranean nation" , "Middle Eastern country" .)
