Independent standing in location upset governing arrangement ... (9)
I believe the answer is:
coalition
'governing arrangement' is the definition.
'independent standing in location upset' is the wordplay.
'standing' says to take the initial letters.
'in' indicates putting letters inside.
'upset' is an anagram indicator.
The initial letter of 'independent' is 'i'.
'location' anagrammed gives 'coaltion'.
'i' put into 'coaltion' is 'COALITION'.
(Other definitions for coalition that I've seen before include "form of government" , "Temporary alliance" , "Alliance of parties" .)
