Eg, godparent or backer (7)
I believe the answer is:
sponsor
This clue is a double definition.
'eg godparent' is the first definition.
(I know that godparent is a type of sponsor)
'backer' is the second definition.
(I've seen this before)
(Other definitions for sponsor that I've seen before include "Promoter; funder" , "Angel" , "Finance (an event)" , "Back financially" , "One paying for, eg, event" .)
