Private meeting's focus for cabinet (6)
I believe the answer is:
closet
'for cabinet' is the definition.
(I've seen this before)
'private meeting's focus' is the wordplay.
'private' becomes 'close' (close can mean private or intimate).
'meeting's' becomes 'date's' (date is a kind of meeting).
'focus' indicates the central letters (focus can mean the centre of something).
The central letter of 'dates' is 't'.
'close'+'t'='CLOSET'
(Other definitions for closet that I've seen before include "Compartment for clothing in the US" , "Shut away in private conference - in small room?" , "Furtive" , "American cupboard or wardrobe" , "secret is revealed" .)
