Financial backer provides new angle (5)
I believe the answer is:
angel
'financial backer' is the definition.
(I've seen this before)
'new angle' is the wordplay.
'new' indicates anagramming the letters.
'angle' is an anagram of 'ANGEL'.
'provides' acts as a link.
(Other definitions for angel that I've seen before include "Theatre financier" , "Investor in a theatrical venture" , "Heavenly messenger" , "one might be recording" , "darling!" .)
