Spain broadcasts competitions (6)
I believe the answer is:
events
'competitions' is the definition.
(I've seen this before)
'spain broadcasts' is the wordplay.
'spain' becomes 'e' (abbreviation for Espana).
'broadcasts' becomes 'vents' (to vent can mean to express or communicate).
'e'+'vents'='EVENTS'
(Other definitions for events that I've seen before include "Important happenings for Steven" , "Horse-riding competitions" , "Occurences, happenings" , "promotions" , "results" .)
