Cheat manipulated sled to bag victory (7)
I believe the answer is:
swindle
'cheat' is the definition.
(both can mean to defraud or deceive)
'manipulated sled to bag victory' is the wordplay.
'manipulated' indicates anagramming the letters.
'to bag' means one lot of letters goes inside another.
'victory' becomes 'win' (a win is a victory).
'sled' anagrammed gives 'sdle'.
'sdle' placed around 'win' is 'SWINDLE'.
(Other definitions for swindle that I've seen before include "Diddle, sting, twist" , "Con, defraud" , "Rip off" , "Cheat (out of money)" , "fleece" .)
