Arrogant person raises bitter (7)

I believe the answer is:

upstart

'arrogant person' is the definition.

'raises bitter' is the wordplay.
'raises' becomes 'ups' (I've seen this before).
'bitter' becomes 'tart' (tart can mean bitter-tasting).
'ups'+'tart'='UPSTART'

(Other definitions for upstart that I've seen before include "Over-assertive newcomer" , "Arrogant person new in high position" , "Bumptious parvenu" , "Bold newcomer" , "Pipsqueak" .)

I've seen this clue in The Sun.
