Helping party with election coming up (6)
I believe the answer is:
dollop
'helping' is the definition.
(I've seen this before)
'party with election coming up' is the wordplay.
'party' becomes 'do' (do is a kind of party).
'with' means one lot of letters go next to another.
'election' becomes 'poll' (I've seen this before).
'coming up' is a reversal indicator (in a down clue, letters go up).
'poll' backwards is 'llop'.
'do'+'llop'='DOLLOP'
(Other definitions for dollop that I've seen before include "Small mass of eg cream" , "Shapeless lump (of food)" , "Quality of eg cream" , "Lump - of custard, perhaps" , "Shapeless mass or lump" .)
