Looking embarrassed about condition being mentioned again (8)
I believe the answer is:
restated
'being mentioned again' is the definition.
'looking embarrassed about condition' is the wordplay.
'looking embarrassed' becomes 'red' (I've seen this before).
'about' means one lot of letters goes inside another.
'condition' becomes 'state' (I've seen this before**).
'red' enclosing 'state' is 'RESTATED'.
(Other definitions for restated that I've seen before include "Didn't tell us anything new" , "Said again" , "In other words" , "Declared, not for the first time" , "Iterated" .)
