Gets off when holding torch, perhaps (7)
I believe the answer is:
alights
'gets off' is the definition.
(I've seen this before)
'when holding torch perhaps' is the wordplay.
'when' becomes 'as'.
'holding' means one lot of letters goes inside another.
'torch perhaps' becomes 'light' (torch is a kind of light).
'as' going around 'light' is 'ALIGHTS'.
(Other definitions for alights that I've seen before include "Touches down" , "Steps down, from a bus say" , "Disembarks" , "Comes down or dismounts" , "Lands" .)
