Petition to exclude a busybody (5)

I believe the answer is:

pryer

'busybody' is the definition.
(someone who pries)

'petition to exclude a' is the wordplay.
'petition' becomes 'prayer' (synonyms).
'to exclude' is a deletion indicator.
'prayer' with 'a' taken away is 'PRYER'.

I've seen this clue in The Times.
