Corresponds with Middle Eastern supporters (7)
I believe the answer is:
tallies
'corresponds' is the definition.
('tally' can be a synonym of 'correspond')
'middle eastern supporters' is the wordplay.
'middle' indicates the central letters.
'supporters' becomes 'allies' (I've seen this before).
The middle letter of 'eastern' is 't'.
't'+'allies'='TALLIES'
'with' is the link.
(Other definitions for tallies that I've seen before include "Reckons debt or score" , "Counts, of votes say" , "Agrees; scores" , "Recordings" , "Sums up" .)
