Conservative less productive, perhaps daily (7)
I believe the answer is:
cleaner
'daily' is the definition.
(dated term for a woman cleaner)
'conservative less productive' is the wordplay.
'conservative' becomes 'C' (UK political abbreviation).
'less productive' becomes 'leaner' (I've seen this before).
'c'+'leaner'='CLEANER'
'perhaps' is the link.
(Other definitions for cleaner that I've seen before include "More sanitary" , "Char; less dirty" , "Eg, char" , "Maybe Daily" , "Chemical agent for removing dirt" .)
