Vote I carry rotten fish (8,3)
I believe the answer is:
electric ray
'fish' is the definition.
(I've seen this before)
'vote i carry rotten' is the wordplay.
'vote' becomes 'elect'.
'rotten' is an anagram indicator.
'i'+'carry'='icarry'
'icarry' is an anagram of 'ricray'.
'elect'+'ricray'='ELECTRIC RAY'
(Other definitions for electric ray that I've seen before include "shocking thing" , "Shocking fish" .)
