Very old African party that is not without love (7)
I believe the answer is:
ancient
'very old' is the definition.
(I've seen this before)
'african party that is not without love' is the wordplay.
'african party' becomes 'anc' (African National Congress, South African party).
'that is' becomes 'ie' (short for Latin 'id est', 'that is').
'without' is a deletion indicator.
'love' becomes 'o' (love means zero in tennis).
'not' with 'o' taken away is 'nt'.
'anc'+'ie'+'nt'='ANCIENT'
(Other definitions for ancient that I've seen before include "Aged and timeworn" , "Antediluvian" , "of long standing" , "Very old, belonging to times long ago" , "showing signs of wear?" .)
