National figure dismantling segregation (5,6)
I believe the answer is:
saint george
'national figure dismantling' is the definition.
I know nothing about this answer so I can't tell whether this works.
'segregation' is the wordplay.
'segregation' can be anagrammed to 'SAINT GEORGE'.
But, I'm unsure how the anagram is indicated.
Can you help me to learn more?
(Other definitions for saint george that I've seen before include "Martyr" , "Legendary dragon-slayer" , "Dragon slayer" , "Henry's patron" , "Patron of several countries including England and Ethiopia" .)
