Statesmen arranged financial enquiry (5,4)
I believe the answer is:
means test
'financial enquiry' is the definition.
'means test' can be an answer for 'enquiry' (means test is a kind of enquiry). I am unsure of the 'financial' bit.
'statesmen arranged' is the wordplay.
'arranged' indicates anagramming the letters.
'statesmen' with letters rearranged gives 'MEANS TEST'.
Can you help me to learn more?
(Other definitions for means test that I've seen before include "form of qualification" , "used to give the benefit" , "it may lead to a benefit" , "resources check" , "financial investigation" .)
