Reportedly, seat of power discarded (6)

I believe the answer is:

thrown

'discarded' is the definition.
Although both the answer and definition are past participle verbs, I cannot see how they can define each other.

'reportedly seat of power' is the wordplay.
'reportedly' indicates a 'sounds like' (homophone) clue.
'seat of power' becomes 'throne' (I've seen this before).
'throne' sounds like 'THROWN'.

Can you help me to learn more?
