Left part of Europe for part of Africa (7)
I believe the answer is:
liberia
'part of africa' is the definition.
(African nation)
'left part of europe' is the wordplay.
'left' becomes 'L' (common abbreviation).
'part of europe' becomes 'iberia' (peninsula including Spain and Portugal).
'l'+'iberia'='LIBERIA'
'for' is the link.
(Other definitions for liberia that I've seen before include "Africa's oldest independent country" , "West African country founded for freed slaves" , "part of Africa" , "W African Republic" , "West African country, capital Monrovia" .)
