Touchy follower has run in unhindered (6)
I believe the answer is:
freely
'unhindered' is the definition.
'touchy follower has run' is the wordplay.
'touchy follower' becomes 'feely' (reference to the phrase 'touchy-feely').
'has' is an insertion indicator.
'run' becomes 'r' (cricket abbreviation).
'feely' placed around 'r' is 'FREELY'.
'in' is the link.
(Other definitions for freely that I've seen before include "Without let or hindrance" , "Liberally; willingly" , "easily" , "boldly" , "Without restriction or payment" .)
