British fruit and nuts (7)
I believe the answer is:
bananas
'nuts' is the definition.
(as in crazy)
'british fruit' is the wordplay.
'british' becomes 'b' (abbreviation e.g. in 'BBC').
'fruit' becomes 'ananas' (ananas is a kind of fruit).
'b'+'ananas'='BANANAS'
'and' is the link.
(Other definitions for bananas that I've seen before include "Crazed" , "nutty" , "Fruit - nuts" , "Mad - curved fruits" , "Fruit; mad" .)
