Foreign capital swelling Conservative vote in dramatic finish (6)
I believe the answer is:
climax
'dramatic finish' is the definition.
'climax' can be an answer for 'finish' (thesaurus). I'm not certain of the 'dramatic' bit.
'foreign capital swelling conservative vote' is the wordplay.
'foreign capital' becomes 'lima' (Lima is an example. I am not sure about the 'foreign' bit.**).
'swelling' means one lot of letters goes inside another ('swell' can mean 'fill').
'conservative' becomes 'c' (abbreviation commonly used in UK politics).
'vote' becomes 'x' (how votes are marked).
'c'+'x'='cx'
'lima' going within 'cx' is 'CLIMAX'.
'in' is the link.
Can you help me to learn more?
(Other definitions for climax that I've seen before include "Peak of emotion" , "Turning point or culmination" , "The decisive moment, in a novel or play say" , "Turning point, moment of greatest intensity" , "(Reach the) highest level" .)
