Content to leave Zimbabwe with many a fanatic (6)
I believe the answer is:
zealot
'a fanatic' is the definition.
(both can mean an extremist)
'content to leave zimbabwe with many' is the wordplay.
'content to leave' says to hollow out the word (remove centre letters) (the contents of the word are removed).
'with' says to put letters next to each other.
'many' becomes 'a lot ' (I've seen this in another clue).
'zimbabwe' with its middle taken out is 'ze'.
'ze'+'alot'='ZEALOT'
(Other definitions for zealot that I've seen before include "Fanatical believer" , "Fervent advocate" , "Fervent enthusiast" , "Fanatic, usually religious" , "A fanatic or extremist" .)
