Good replacement for leader of Zambia in another country (6)
I believe the answer is:
gambia
'leader of zambia in another country' is the definition.
'Gambia' can be an answer for 'country' (Gambia is an African country). I am not sure about the 'leader of zambia in another' bit.
'good replacement' is the wordplay.
'good' becomes 'g' (abbreviation).
'replacement' becomes 'ambia' (I can't justify this - if you can you should believe this answer much more).
'g'+'ambia'='GAMBIA'
'for' is the link.
Can you help me to learn more?
(Other definitions for gambia that I've seen before include "West African country surrounded by Senegal" , "West African river" , "Aim bag toward African state" , "West African country, capital Banjul" .)
