Took a seat from Liberal in elite celestial body (9)
I believe the answer is:
satellite
'celestial body' is the definition.
(satellite is a kind of celestial body)
'took a seat from liberal in elite' is the wordplay.
'took a seat' becomes 'sat' (I've seen this before).
'from' is a charade indicator (letters next to each other).
'liberal' becomes 'l' (abbreviation).
'in' is an insertion indicator.
'l' inserted into 'elite' is 'ellite'.
'sat'+'ellite'='SATELLITE'
(Other definitions for satellite that I've seen before include "Country dependent on another" , "Part of telecoms system" , "important person's attendant" , "Body in orbit around another" , "Something in orbit" .)
