A bit more but not all about one facing charges? (7)
I believe the answer is:
matador
'one facing charges?' is the definition.
(a matador is charged at by bulls)
'a bit more but not all about' is the wordplay.
'bit' becomes 'tad' (I've seen this before**).
'but not all' means to remove the last letter.
'about' is an insertion indicator.
'more' with its last letter taken away is 'mor'.
'a'+'tad'='atad'
'atad' placed within 'mor' is 'MATADOR'.
(Other definitions for matador that I've seen before include "fighter in the ring?" , "paid killer" , "A Spanish bullfighter" , "He kills the bull in formal fight" , "he aims to get a bull" .)
