Blonde head showing impartiality (8)
I believe the answer is:
fairness
'impartiality' is the definition.
(I know that fairness is a type of impartiality)
'blonde head' is the wordplay.
'blonde' becomes 'fair' (similar in meaning).
'head' becomes 'ness' (type of geographical point).
'fair'+'ness'='FAIRNESS'
'showing' is the link.
(Other definitions for fairness that I've seen before include "Equality" , "Impartiality, justice" , "the fine, dry state of the weather" , "Beauty - justice" , "Equity, justice" .)
