Vote for English held in the Spanish court (5)
I believe the answer is:
elect
'vote for' is the definition.
(I've seen this before)
'english held in the spanish court' is the wordplay.
'english' becomes 'E' (abbreviation).
'held in' means one lot of letters goes inside another.
'the spanish' becomes 'el' ('the' in Spanish).
'court' becomes 'ct' (abbreviation used in road names).
'el'+'ct'='elct'
'e' placed within 'elct' is 'ELECT'.
(Other definitions for elect that I've seen before include "Choose; singled out" , "Chosen - to vote" , "Put into power through the ballot box" , "Waiting to get into office" , "Preferred" .)
