Ends broadcast about European requirements (5)
I believe the answer is:
needs
'requirements' is the definition.
('need' can be a synonym of 'requirement')
'ends broadcast about european' is the wordplay.
'broadcast' indicates anagramming the letters (letters scattered or cast around).
'about' means one lot of letters goes inside another.
'european' becomes 'e' (abbreviation e.g. EU).
'ends' is an anagram of 'neds'.
'neds' going around 'e' is 'NEEDS'.
(Other definitions for needs that I've seen before include "Requirements" , "Is desperate for" , "Essentials" , "Requires or lacks" , "Demands" .)
