Political leaders ordered means test (9)
I believe the answer is:
statesmen
'political leaders' is the definition.
(statesman is a kind of political leader)
'ordered means test' is the wordplay.
'ordered' is an anagram indicator.
'means'+'test'='meanstest'
'meanstest' with letters rearranged gives 'STATESMEN'.
(Other definitions for statesmen that I've seen before include "Political figures" , "Means test for people distinguished in service to the people" , "Males prominent in their countries affairs" , "Males prominent and skilled in government" , "Means test for males prominent in national affairs" .)
