Top bishop has Father Ted defrocked (4)
I believe the answer is:
pope
'top bishop' is the definition.
(I've seen this before)
'father ted defrocked' is the wordplay.
I cannot really see how this works, but
'father' could be 'pop' (pop is a kind of father) and 'pop' is found in the answer.
A single letter 'e' remains which might be clued in a way I don't understand.
This may be the basis of clue (or it may be nonsense).
'has' is the link.
Can you help me to learn more?
(Other definitions for pope that I've seen before include "Writer" , "Pontiff" , "freshwater fish" , "Well-versed man" , "Francis < Alexander" .)
