Rubbish a politician’s spinning (8)
I believe the answer is:
rotatory
'spinning' is the definition.
(I've seen this before)
'rubbish a politician's' is the wordplay.
'rubbish' becomes 'rot' (I've seen this before).
'politician' becomes 'tory' (I've seen this before).
'rot'+'a'+'tory'='ROTATORY'
(Other definitions for rotatory that I've seen before include "Associated with spinning" , "Going round" , "circular route?" , "Turning like a wheel" , "Revolutionary" .)
