The Spanish board will accept European Community is capable of winning votes (9)
I believe the answer is:
electable
'capable of winning votes' is the definition.
(able to win an election)
'the spanish board will accept european community' is the wordplay.
'the spanish' becomes 'el' ('the' in Spanish).
'board' becomes 'table' (both can mean food).
'will accept' indicates putting letters inside.
'european community' becomes 'EC' (abbreviation).
'el'+'table'='eltable'
'eltable' going around 'ec' is 'ELECTABLE'.
'is' acts as a link.
(Other definitions for electable that I've seen before include "Likely to attract votes" , "might be put in office" .)
