Launch programme with a vote, getting zero support (6)
I believe the answer is:
apollo
'launch programme' is the definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
'a vote getting zero support' is the wordplay.
'vote' becomes 'poll' (polling is a kind of voting).
'getting' is a charade indicator (letters next to each other).
'zero' becomes 'O' (O resembles 0).
'support' says to put letters next to each other (in a down clue, some letters hold others up).
'a'+'poll'+'o'='APOLLO'
'with' is the link.
Can you help me to learn more?
(Other definitions for apollo that I've seen before include "US space program" , "Handsome Greek god" , "US spacecraft" , "Programme targeting satellite" , "Fair youth" .)
