Get together, unveiling new initiative to elect leaders (5)
I believe the answer is:
unite
'get together' is the definition.
(uniting is a kind of getting together)
'unveiling new initiative to elect leaders' is the wordplay.
'leaders' indicates taking the first letters.
The first letters of 'unveiling new initiative to elect' is 'UNITE'.
(Other definitions for unite that I've seen before include "Join together, become allies" , "pool resources" , "Join together, merge" , "Combine - join" , "Put together" .)
