Maybe Universal Credit has advantage (7)
I believe the answer is:
benefit
This clue is a double definition.
'maybe universal credit' is the first definition.
(UK universal credit is a government benefit)
'advantage' is the second definition.
(I've seen this in another clue)
'has' acts as a link.
(Other definitions for benefit that I've seen before include "Fine bet on to produce an advantage" , "Advantage or profit gained from something" , "Charity event" , "(Gain) advantage" , "Payment" .)
