Rwanda - er, wrong approach (4,4)
I believe the answer is:
draw near
'approach' is the definition.
(I know that approach can be written as draw near)
'rwanda er wrong' is the wordplay.
'wrong' is an anagram indicator.
'rwanda'+'er'='rwandaer'
'rwandaer' is an anagram of 'DRAW NEAR'.
(Other definitions for draw near that I've seen before include "Approach" , "get closer" , "Come close" .)
