Surprised comment about world leader yielding power in rebellion (6)
I believe the answer is:
mutiny
'power in rebellion' is the definition.
'mutiny' can be an answer for 'rebellion' (mutiny is a kind of rebellion). I'm not certain of the 'power in' bit.
'surprised comment about world leader' is the wordplay.
'surprised comment' becomes 'my' (expression of surprise).
'about' indicates putting letters inside.
'world leader' becomes 'utin' (I can't explain this - if you can you should believe this answer much more).
'my' going around 'utin' is 'MUTINY'.
'yielding' is the link.
Can you help me to learn more?
(Other definitions for mutiny that I've seen before include "Open rebellion by sailors or soldiers" , "Open rebellion against constituted authority" , "Military rebellion" , "Rebellion in the armed forces" , "Revolt against authority" .)
