Unseated from chair of state, reportedly (6)
I believe the answer is:
thrown
'unseated' is the definition.
(I've seen this before)
'chair of state reportedly' is the wordplay.
'chair of state' becomes 'throne' (I've seen this before).
'reportedly' indicates a 'sounds like' (homophone) clue.
'throne' sounds like 'THROWN'.
'from' acts as a link.
(Other definitions for thrown that I've seen before include "Tossed" , "Disconcerted; chucked" , "given up intentionally" , "Having been projected through the air" , "Unseated" .)
