Celebrate no leader getting salary increase (5)
I believe the answer is:
raise
'salary increase' is the definition.
(I've seen this before)
'celebrate no leader' is the wordplay.
'celebrate' becomes 'praise'.
'no leader' means to remove the first letter.
'praise' with its first letter taken off is 'RAISE'.
'getting' is the link.
(Other definitions for raise that I've seen before include "Bring up - an increase in pay" , "Wage increase" , "jack up" , "Produce" , "Increase; elevate" .)
