Citizen having say in veto (8)

Ross

I believe the answer is:

negative

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

'veto' is the definition.
(I know that veto can be written as negative)

'citizen having say' is the wordplay.
'citizen' becomes 'native' (I can't explain this - if you can you should give a lot more credence to this answer).
'having' is an insertion indicator.
'say' becomes 'eg' (both can mean 'for example').
'native' enclosing 'eg' is 'NEGATIVE'.

'in' acts as a link.

Can you help me to learn more?

(Other definitions for negative that I've seen before include "image for a developer" , "Denying" , "Early form of photo" , "Opposite of affirmative" , "Piece of photographic film" .)
