Responsible person? (7)

I believe the answer is:

culprit

'responsible person?' is the definition.

This is all the clue.

(Other definitions for culprit that I've seen before include "one awaiting trial" , "The one responsible for a crime" , "Person responsible for wrongdoing" , "The person to blame, the guilty one" , "he should have conviction" .)

I've seen this clue in The Sun.
