Spin rubbish at end of conference (6)
I believe the answer is:
rotate
'spin' is the definition.
(I know that spin is a more specific form of the action rotate)
'rubbish at end of conference' is the wordplay.
'rubbish' becomes 'rot' (both can mean nonsense).
'end of' says to take the final letters.
The last letter of 'conference' is 'e'.
'rot'+'at'+'e'='ROTATE'
(Other definitions for rotate that I've seen before include "'Er, to a T? (anag)" , "Go round and round" , "Turn round" , "roll" , "Turn around as on axle or spit" .)
