Margaret's place in Wimbledon history (5)
I believe the answer is:
court
'place in wimbledon history' is the definition.
'court' can be an answer for 'place' (thesaurus). I am not sure about the 'in wimbledon history' bit.
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for court that I've seen before include "Judicial tribunal" , "The Yard" , "Woo - where tennis is played" , "sovereign's advisers" , "Hall of justice" .)
