Manual inspiring African politicians to show leadership (8)
I believe the answer is:
guidance
'leadership' is the definition.
(I've seen this before)
'manual inspiring african politicians' is the wordplay.
'manual' becomes 'guide' (guidebook).
'inspiring' indicates putting letters inside.
'african politicians' becomes 'anc' (African National Congress, South African party).
'guide' going around 'anc' is 'GUIDANCE'.
'to show' is the link.
(Other definitions for guidance that I've seen before include "Advice, assistance" , "Missile component" , "Help, advice or counselling" , "Help in choice of action" , "instruction" .)
