Withdraw wine close to unpalatable around church (6)
I believe the answer is:
recede
'withdraw' is the definition.
('recede' can be a synonym of 'withdraw')
'wine close to unpalatable around church' is the wordplay.
'wine' becomes 'red' (red wine is a kind of wine**).
'close to' indicates one should take the final letters (the close/ending of).
'around' means one lot of letters goes inside another.
'church' becomes 'ce' (abbreviation for Church of England).
The last letter of 'unpalatable' is 'e'.
'red'+'e'='rede'
'rede' placed around 'ce' is 'RECEDE'.
(Other definitions for recede that I've seen before include "Move backward" , "Go backwards" , "Decline" , "Start balding" , "Decree (anag) - ebb" .)
