In the best position to suppress opposition (2,3)
I believe the answer is:
on top
'in' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.
'best position to suppress opposition' is the wordplay.
I cannot really see how this works, but
'best' could be 'top' (top can mean the very best) and 'top' is located in the answer.
The remaining letters 'on' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
'the' is the link.
Can you help me to learn more?
(Other definitions for on top that I've seen before include "At the summit or in superior position" , "In a dominant position" , "Leading" , "Winning" .)
