Approves of indications of support (7)
I believe the answer is:
favours
This clue is a double definition.
'approves' is the first definition.
(I've seen this before)
'indications of support' is the second definition.
(I've seen this before)
'of' is the link.
(Other definitions for favours that I've seen before include "Approves" , "indications of support" , "Supports or prefers one thing or person over another" , "Good turns" .)
