Leave theatrical role (4)

I believe the answer is:

part

This clue is a double definition.

'leave' is the first definition.
(parting is a kind of leaving)

'theatrical role' is the second definition.
('part' can be a synonym of 'theatrical role')

(Other definitions for part that I've seen before include "Separate - role" , "Piece; divide" , "Fraction of the whole - separate" , "Component; divide" , "Portion of a whole" .)

I've seen this clue in The Telegraph.
