God turned up in Benidorm (4)
I believe the answer is:
odin
'god' is the definition.
(Odin is an example)
'turned up in benidorm' is the wordplay.
'turned up' shows that the letters should be reversed in order.
'in' indicates the answer is hidden within the clue.
'nido' is hidden in the letters of 'benidorm'.
'nido' in reverse letter order is 'ODIN'.
(Other definitions for odin that I've seen before include "an all-powerful one" , "Supreme Scandinavian god - what a racket" , "Mythological Norse god of war" , "Norse god, husband of Frigg, father of Thor" , "Supreme Norse deity" .)
