Handle championship (5)
I believe the answer is:
title
This clue is a double definition.
'handle' is the first definition.
(I've seen this before)
'championship' is the second definition.
(a championship is a sporting title)
(Other definitions for title that I've seen before include "'The name of a book, say (5)'" , "Document showing legal right to possess a property" , "Name, honorific" , "Right to possession" , "Lord, sir, doctor etc." .)
