Dishonestly manipulating tackle (7)
I believe the answer is:
rigging
This might be a double definition.
'dishonestly manipulating' is the first definition.
'rigging' can be an answer for 'manipulating' ('rig' can be a synonym of 'manipulate'). I'm not certain of the 'dishonestly' bit.
'tackle' is the second definition.
(I know that tackle can be written as rigging)
Can you help me to learn more?
(Other definitions for rigging that I've seen before include "Manipulation" , "Ship's tackle" , "Ship's ropes etc." , "vote-manipulating" , "Ropes, etc, on a sailing ship" .)
