Rector finds Polish leader lighting fires (6)
I believe the answer is:
parson
'rector' is the definition.
(I know that rector can be written as parson)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for parson that I've seen before include "Minister of religion" , "Rector; clergyman" , "Aprons (anag.)" , "A rector or vicar" , "Churchman" .)
