In back with Carson a former Soviet leader (6)

I believe the answer is:

nikita

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

'former soviet leader' is the definition.
The definition suggests a singular noun which matches the answer.

'in back with carson a' is the wordplay.
'back' is a reversal indicator.
'with' is a charade indicator (letters next to each other).
'carson' becomes 'kit' (I've seen this in another clue).
'in' written backwards gives 'ni'.
'ni'+'kit'+'a'='NIKITA'

Can you help me to learn more?

(Another definition for nikita that I've seen is " ... Khrushchev".)

I've seen this clue in the Sydney Morning Herald.
