Lead driver is golf contest scandal (8)
I believe the answer is:
disgrace
'scandal' is the definition.
(I've seen this before)
'lead driver is golf contest' is the wordplay.
'lead driver' becomes 'dis' (I can't justify this - if you can you should believe this answer much more).
'is golf' becomes 'g' (phonetic alphabet: alpha, bravo, charlie etc.).
'contest' becomes 'race' (race is a kind of contest).
'dis'+'g'+'race'='DISGRACE'
Can you help me to learn more?
(Other definitions for disgrace that I've seen before include "scandal" , "Loss of good reputation" , "Loss of honour" , "Cadger is in state of ignominy" , "State of dishonour" .)
