Leader in dance is wrong to twist (7)
I believe the answer is:
distort
'twist' is the definition.
(distorting is a kind of twisting)
'leader in dance is wrong' is the wordplay.
'leader in' indicates taking the first letters.
'wrong' becomes 'tort' (a civil wrong in law).
The initial letter of 'dance' is 'd'.
'd'+'is'+'tort'='DISTORT'
'to' is the link.
(Other definitions for distort that I've seen before include "Pervert" , "Warp" , "Twist out of shape" , "turn crooked" , "Deform" .)
