Radio covering end of Italy's dictatorship (7)
I believe the answer is:
tyranny
'dictatorship' is the definition.
(I know that dictatorship can be written as tyranny)
'radio covering end of italy's' is the wordplay.
'radio' becomes 'tranny' (short for transistor radio).
'covering' means one lot of letters goes inside another.
'end of' indicates one should take the final letters.
The final letter of 'italy' is 'y'.
'tranny' going around 'y' is 'TYRANNY'.
(Other definitions for tyranny that I've seen before include "Oppression" , "Oppressive government" , "Form of despotism" , "Cruel and arbitrary rule" , "Cruel rulers" .)
