Trust new support (5)

I believe the answer is:

strut

'support' is the definition.
(strut is a kind of support)

'trust new' is the wordplay.
'new' is an anagram indicator.
'trust' is an anagram of 'STRUT'.

(Other definitions for strut that I've seen before include "Stiffening bar" , "Supportive member" , "Strengthening bar" , "Walk with a lofty proud gait" , "Brace; swagger" .)

I've seen this clue in The Mirror.
