Moral focus with conservative rhetoric (7)
I believe the answer is:
oratory
'rhetoric' is the definition.
(both can mean formal speech)
'moral focus with conservative' is the wordplay.
'focus' says to take the centre (focus can mean the centre of something).
'with' means one lot of letters go next to another.
'conservative' becomes 'tory' (informal term for a Conservative Party member).
The middle of 'moral' is 'ora'.
'ora'+'tory'='ORATORY'
(Other definitions for oratory that I've seen before include "Place for private prayer" , "Gift of the gab" , "School" , "Rhetoric - chapel" , "Formal speech-making, could be pompous" .)
