Pope's support complete for untrue tale (5,6)

'tale' is the definition.
(I know that urban legend is a type of anecdote)

'pope's support complete for untrue' is the wordplay.
I cannot quite see how this works, but
'support' could be 'leg' (leg is a kind of support) and 'leg' is present in the answer.
'complete' could be 'end' (I've seen this before) and 'end' is present in the answer.
'pope' could be 'urban' (there have been several Pope Urbans) and 'urban' is located in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
