Trunk revealed in part of Manchester (5)
I believe the answer is:
chest
'trunk' is the definition.
(I've seen this in another clue)
'part of manchester' is the wordplay.
'part of' indicates the answer is hidden within the clue.
'CHEST' can be found hidden inside 'manchester'.
'revealed in' is the link.
(Other definitions for chest that I've seen before include "ark" , "Large box; thorax" , "Trunk or crate" , "It's enclosed by the ribs" , "Treasure (or heart) container" .)
