Skin taken from disloyal follower in uprising (4)
I believe the answer is:
flay
'skin' is the definition.
(flay can mean to take something's skin off)
'disloyal follower in uprising' is the wordplay.
'in' indicates the answer is hidden within the clue.
'uprising' is a reversal indicator.
'yalf' can be found hidden inside 'disloyal follower'.
'yalf' backwards is 'FLAY'.
'taken from' is the link.
(Other definitions for flay that I've seen before include "Strip skin from (a body)" , "Slate" , "Savagely criticise; skin" , "Fiercely criticise" , "Strip skin off by whipping" .)
