Negligent concerning failure (6)

I believe the answer is:

remiss

'negligent' is the definition.
('remiss' can be similar in meaning to 'negligent')

'concerning failure' is the wordplay.
'concerning' becomes 're'.
'failure' becomes 'miss' (miss is a kind of failure).
're'+'miss'='REMISS'

(Other definitions for remiss that I've seen before include "Lacking attention to duty" , "Lacking care to duty" , "Careless and inattentive" , "Negligent, lax" , "At fault" .)

I've seen this clue in The Telegraph.
