Expel one political wing completely (8)
I believe the answer is:
outright
'completely' is the definition.
(outright means completely or totally)
'expel one political wing' is the wordplay.
I cannot really see how this works, but
'one' could be 'o' (I've seen this in other clues) and 'o' is present in the answer.
'wing' could be 'right' and 'right' is found within the answer.
The remaining letters 'ut' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for outright that I've seen before include "straight away" , "Without reservation or stipulation" , "Completely - immediately" , "Unreservedly" , "Completely - undisputed" .)
