Clubs overhaul declaration of faith (5)
I believe the answer is:
credo
'declaration of faith' is the definition.
'credo' can be an answer for 'faith' (I've seen this before). I am unsure of the 'declaration of' bit.
'clubs overhaul' is the wordplay.
'clubs' becomes 'c' (abbreviation used in card games such as bridge).
'overhaul' becomes 're-do' (I've seen this in another clue).
'c'+'redo'='CREDO'
Can you help me to learn more?
(Other definitions for credo that I've seen before include "Belief system" , "Formal statement of beliefs" , "Words to live by; belief" , "System of principles" , "mission statement" .)
