Drink with English church leader (4)
I believe the answer is:
pope
'church leader' is the definition.
(I've seen this in another clue)
'drink with english' is the wordplay.
'drink' becomes 'pop' (pop is a kind of drink).
'with' means one lot of letters go next to another.
'english' becomes 'e' (abbreviation).
'pop'+'e'='POPE'
(Other definitions for pope that I've seen before include "Head of RC church" , "Francis < Alexander" , "Vatican leader" , "Writer" , "Poet - religious leader" .)
