Peers at broken laser (5)
I believe the answer is:
earls
'peers' is the definition.
(I know this)
'broken laser' is the wordplay.
'broken' is an anagram indicator.
'laser' is an anagram of 'EARLS'.
'at' acts as a link.
(Other definitions for earls that I've seen before include "Noblemen (with a Court?)" , "They're below marquess and above viscount" , "Nobles" , "Laser the British peers" , "Lear's out for the flight of the nobility" .)
