Capital Radio presenter also called to attend car crash? (8)
I believe the answer is:
djakarta
'capital' is the definition.
(Djakarta is the capital of Indonesia)
'radio presenter also called to attend car crash?' is the wordplay.
'radio presenter' becomes 'DJ'.
'also called' becomes 'aka' (also known as).
'to attend' says to put letters next to each other.
'car crash?' becomes 'RTA' (abbreviation for road traffic accident).
'dj'+'aka'+'rta'='DJAKARTA'
(Other definitions for djakarta that I've seen before include "Capital of Indonesia" , "Indonesian city" , "Indonesian capital (Former sp.)" .)
