Report rogue - the one carrying baggage (6)
I believe the answer is:
Here is my best explanation:
'the one carrying baggage' is the definition.
I can't tell whether this defines the answer.
'report rogue' is the subsidiary indication.
'rogue' indicates anagramming the letters.
'report' anagrammed gives 'porter'.
(Other definitions for porter that I've seen before include "Hotel bag-carrier or dark beer", "Hotel luggage carrier", "Railway worker; the Ruler of the Queen's Navee (G&S)", "Carrier; beer", "Baggage-handler", "One with a burden", "Bearer", "Stout", "Doorkeeper; dark beer" and "He should be able to carry".)
