Important figure in wildest Kenya (3,3)

I believe the answer is:

key man

I'm a little stuck... Click here to teach me more about this clue!

'wildest kenya' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.

'important figure' is the wordplay.
'important' becomes 'key' (similar in meaning).
'figure' becomes 'man' (I can't explain this - if you can you should believe this answer much more).
'key'+'man'='KEY MAN'

'in' acts as a link.

Can you help me to learn more?

I've seen this clue in the Evening Standard.
