Rubbish a right-winger going round (8)
I believe the answer is:
rotatory
'going round' is the definition.
(I've seen this before)
'rubbish a right-winger' is the wordplay.
'rubbish' becomes 'rot' (I've seen this before).
'right-winger' becomes 'tory' (Tory is an example).
'rot'+'a'+'tory'='ROTATORY'
(Other definitions for rotatory that I've seen before include "Turning like a wheel" , "Revolutionary" , "Associated with spinning" , "Going round" , "Revolving about an axis" .)
