A dazzling display amid applause for racing driver (10)
I believe the answer is:
charioteer
'racing driver' is the definition.
'a dazzling display amid applause' is the wordplay.
'dazzling display' becomes 'riot'.
'amid' indicates putting letters inside.
'applause' becomes 'cheer'.
'a'+'riot'='ariot'
'ariot' inserted into 'cheer' is 'CHARIOTEER'.
'for' is the link.
(Other definitions for charioteer that I've seen before include "chap driving old vehicle" , "Ben Hur?" , "Hippodrome racer" , "Driver of Roman vehicle" , "Driver common in early warfare" .)
