Bali without a leader of course, after Peru sacked country such as Indonesia (8)
I believe the answer is:
republic
'country such as indonesia' is the definition.
I can't judge whether this definition defines the answer.
'bali without a leader of course after peru sacked' is the wordplay.
'without' indicates named letters should be taken away.
'leader of course' becomes 'c' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'after' is a charade indicator (letters next to each other).
'sacked' is an anagram indicator.
'bali' with 'a' taken away is 'bli'.
'peru' with letters rearranged gives 'repu'.
'bli'+'c'='blic'
'blic' after 'repu' is 'REPUBLIC'.
Can you help me to learn more?
(Other definitions for republic that I've seen before include "State in which the people hold the power" , "Country with no king" , "France, for example, is one" , "See 17" , "Commonwealth" .)
