In England, I am top guy! (7,3)
I believe the answer is:
leading man
'top guy' is the definition.
The answer and definition can be both people as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'in england i am' is the wordplay.
'england i am' anagrams to 'LEADING MAN'.
However, I'm unsure how the anagram is indicated.
Can you help me to learn more?
(Other definitions for leading man that I've seen before include "Chief actor" , "megastar?" , "Principal actor" , "Protagonist" , "top fellow on stage" .)
