Insurer redrafted weird return (11)
I believe the answer is:
underwriter
'insurer' is the definition.
(I know that insurer can be written as underwriter)
'redrafted weird return' is the wordplay.
'redrafted' indicates an anagram (to redraft something is to improve or rewrite it).
'weird'+'return'='weirdreturn'
'weirdreturn' with letters rearranged gives 'UNDERWRITER'.
(Other definitions for underwriter that I've seen before include "Financial guarantor" , "One in the insurance business" , "Shipbroker" , "Person in the insurance business" , "Insurance man" .)
