Once again find left-winger is getting protection (10)
I believe the answer is:
rediscover
'once again find' is the definition.
('discover' can be a synonym for 'find' so perhaps 'rediscover' is OK for 'once again find')
'left-winger is getting protection' is the wordplay.
'left-winger' becomes 'red' (red is a kind of left-winger).
'getting' says to put letters next to each other.
'protection' becomes 'cover'.
'red'+'is'+'cover'='REDISCOVER'
(Other definitions for rediscover that I've seen before include "Not for the first time, find" , "Find encore" , "Spy out again" .)
