Freedom in African country I discounted? Not I, after revolution (10)

Ross

I believe the answer is:

liberation

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

'freedom' is the definition.
(I know that Liberation is a liberation)

'in african country i discounted? not i after revolution' is the wordplay.
I cannot really understand how this works, but
'i' could be 'a' and 'a' is present in the answer.
'not' could be 'o' (I've seen this in other clues) and 'o' is present in the answer.
'in' is present in the answer.
This explanation may well be incorrect...

Can you help me to learn more?

(Other definitions for liberation that I've seen before include "Act of freeing" , "Deliverance" , "Release" , "Act of setting free" .)

I've seen this clue in The Independent.
