Lying tout beaten up? It wasn’t me! (3,6)
I believe the answer is:
not guilty
'it wasn't me' is the definition.
(both might be said when claiming innocence)
'lying tout beaten up?' is the wordplay.
'beaten up?' indicates anagramming the letters.
'lying'+'tout'='lyingtout'
'lyingtout' anagrammed gives 'NOT GUILTY'.
(Other definitions for not guilty that I've seen before include "Verdict" , "Innocent" , "Common plea by accused in court" .)
