Chancellor of the Exchequer supporting unqualified bankers in autumn statement (9)
I believe the answer is:
utterance
'statement' is the definition.
(I've seen this in another clue)
'chancellor of the exchequer supporting unqualified bankers in autumn' is the wordplay.
'chancellor of the exchequer' becomes 'ce' (I've seen this in other clues).
'supporting' says to put letters next to each other (in a down clue, some letters go below others).
'unqualified' becomes 'utter' (I've seen this in another clue).
'bankers in autumn' becomes 'an' (I can't explain this - if you can you should give a lot more credence to this answer).
'utter'+'an'='utteran'
'ce' put after 'utteran' is 'UTTERANCE'.
Can you help me to learn more?
(Other definitions for utterance that I've seen before include "Statement" , "sermon, say" , "Something said" , "Spoken word(s)" , "Remark" .)
