Allege beauty mostly misrepresented in sports ranking (6,5)
I believe the answer is:
league table
'sports ranking' is the definition.
(a ranking of teams in a league)
'allege beauty mostly misrepresented' is the wordplay.
'mostly' means to remove the last letter.
'misrepresented' indicates anagramming the letters.
'allege'+'beauty'='allegebeauty'
'allegebeauty' with its last letter taken off is 'allegebeaut'.
'allegebeaut' anagrammed gives 'LEAGUE TABLE'.
'in' acts as a link.
(Other definitions for league table that I've seen before include "Team ranking" , "record of sporting achievement" , "Chart of competitors" , "List of teams setting out their relative performance" , "Comparison of merit" .)
