Setter's lighter stakeholder? (7)

I believe the answer is:

impaler

'stakeholder?' is the definition.
(I have seen 'murderous stakeholder' mean 'impaler' so perhaps 'stakeholder' could also mean 'impaler')

'setter's lighter' is the wordplay.
'setter's' becomes 'I'm' (I've seen this in other clues).
'lighter' becomes 'paler' ('pale' can be similar in meaning to 'light').
'im'+'paler'='IMPALER'

(Another definition for impaler that I've seen is " murderous stakeholder".)

I've seen this clue in The Guardian.
