Just once, late in the day, husband meeting with journalist (4-6)
I believe the answer is:
even-handed
'just' is the definition.
(I've seen this before)
'late in the day husband meeting with journalist' is the wordplay.
'late in the day' becomes 'even' (I've seen this before).
'husband' becomes 'h' (abbreviation).
'meeting' is a charade indicator (letters next to each other).
'with' becomes 'and'.
'journalist' becomes 'ed' (short for editor).
'even'+'h'+'and'+'ed'='EVEN-HANDED'
'once' acts as a link.
(Another definition for even-handed that I've seen is " Fair, impartial".)
