Prevent individual associated with Tory leader getting title (7)
I believe the answer is:
baronet
'title' is the definition.
(I've seen this before)
'prevent individual associated with tory leader' is the wordplay.
'prevent' becomes 'bar' (both can mean to ban or disallow).
'individual' becomes 'one' (an individual is one person).
'associated with' is a charade indicator (letters next to each other).
'leader' indicates taking the first letters.
The first letter of 'tory' is 't'.
'bar'+'one'+'t'='BARONET'
'getting' is the link.
(Other definitions for baronet that I've seen before include "Lowest hereditary title of honour" , "Hereditary knight" , "A Breton could be a British peer" , "Minor noble" , "A Bronte (anag.)" .)
