Some tribunal at Chelsea, perhaps (3)
I believe the answer is:
bun
'chelsea perhaps' is the definition.
I can't judge whether this definition defines the answer.
'some tribunal at' is the wordplay.
'some' says the answer is hidden in the clue (some of the parts of the word are used).
'BUN' is hidden within 'tribunal at'.
Can you help me to learn more?
(Other definitions for bun that I've seen before include "A small cake, sweet and round" , "Small cake - tied-up hair" , "Kind of small round cake" , "Hairstyle, cake" , "Small cake; hair style" .)
