Bankrupt papa loves Radiohead (4)
I believe the answer is:
poor
'bankrupt' is the definition.
(thesaurus)
'papa loves radiohead' is the wordplay.
'papa' becomes 'P' (NATO / phonetic alphabet).
'loves' becomes 'oo' (love means 0 in tennis).
'radiohead' becomes 'r' (head letter of 'radio').
'p'+'oo'+'r'='POOR'
(Other definitions for poor that I've seen before include "Lacking means; paltry" , "Mere" , "Of inferior standard" , "Pants" , "Of inferior quality or means" .)
