Place is indeed filled in (9)

I believe the answer is:

deputised

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

'place is indeed filled in' is the definition.
I can't judge whether this definition defines the answer.

'is indeed filled in' is the wordplay.
'indeed filled' becomes 'deputed' (I can't explain this - if you can you should believe this answer much more).
'in' is an insertion indicator.
'is' placed inside 'deputed' is 'DEPUTISED'.

Can you help me to learn more?

(Another definition for deputised that I've seen is " Stood in (for)".)

I've seen this clue in The Daily Express.
