Clean it up, shifting blame (9)
I believe the answer is:
inculpate
'blame' is the definition.
(I've seen this before)
'clean it up shifting' is the wordplay.
'shifting' indicates an anagram.
'clean'+'it'+'up'='cleanitup'
'cleanitup' with letters rearranged gives 'INCULPATE'.
(Other definitions for inculpate that I've seen before include "Blame" , "Accuse" , "Incriminate" .)
