Showman takes prime position, as backed by Olympic host (10)
I believe the answer is:
impresario
'showman' is the definition.
(synonyms)
'prime position as backed by olympic host' is the wordplay.
I cannot quite understand how this works, but
an anagram of 'prime' is 'impre' which is present in the answer.
This may be the basis of clue (or it may be nonsense).
'takes' is the link.
Can you help me to learn more?
(Other definitions for impresario that I've seen before include "Arranger of concerts, etc" , "Theatrical entrepreneur" , "artistic director" , "Entertainer" , "Theatrical organiser" .)
