Take in late follower (9)
I believe the answer is:
conformer
'follower' is the definition.
(someone who follows or conforms)
'take in late' is the wordplay.
'take in' becomes 'con' (I've seen this in another clue).
'late' becomes 'former' (I've seen this before).
'con'+'former'='CONFORMER'
(Other definitions for conformer that I've seen before include "one obeying the law?" , "fitter" .)
