Corrective to fix a conservative (10)

I believe the answer is:

amendatory

'corrective' is the definition.
(I've seen this in another clue)

'fix a conservative' is the wordplay.
'fix' becomes 'amend' (to amend is to fix or sort out).
'conservative' becomes 'tory' (Tory means a member of the Conservative Party).
'amend'+'a'+'tory'='AMENDATORY'

'to' acts as a link.

(Another definition for amendatory that I've seen is " putting things right".)

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