Manage to get a ladder (3)
I believe the answer is:
run
I believe this clue is a triple definition!
'manage' is the first definition.
(both can mean to organise)
'to get' is the second definition.
(running is a kind of getting)
'a ladder' is the third definition.
(both can mean a tear in tights)
(Other definitions for run that I've seen before include "goal for England player?" , "Race; flee" , "string of performances" , "Possibly an extra" , "On the . . . - fleeing from pursuit" .)
