Throw Austen out (6)
I believe the answer is:
unseat
'throw' is the definition.
(thesaurus)
'austen out' is the wordplay.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'austen' anagrammed gives 'UNSEAT'.
(Other definitions for unseat that I've seen before include "Cause to fall from the saddle" , "Dislodge from saddle" , "Remove from power" , "Throw (as a 15?)" , "Remove from horse (or house?)" .)
