Nervous about Tory leader being bland (7)
I believe the answer is:
neutral
'bland' is the definition.
(I've seen this before)
'nervous about tory leader' is the wordplay.
'nervous' becomes 'neural' ('neural' can be a synonym of 'nervous').
'about' means one lot of letters goes inside another.
'tory leader' becomes 't' (I've seen this in other clues).
'neural' placed around 't' is 'NEUTRAL'.
'being' is the link.
(Other definitions for neutral that I've seen before include "nondescript colour" , "gear drivers are still in" , "Where gears are not engaged" , "Having no decided colour" , "Not partisan or supporting either side in dispute" .)
