Blunt Tory leader's language (5)
I believe the answer is:
terse
'blunt' is the definition.
(thesaurus)
'tory leader's language' is the wordplay.
'tory leader' becomes 't' (I've seen this in other clues).
'language' becomes 'erse' (Erse is an example).
't'+'erse'='TERSE'
(Other definitions for terse that I've seen before include "Short and succinct" , "precise" , "Short and sharp" , "Abrupt, concise" , "Brief and to the point" .)
