Tough issue to handle (3,6)
I believe the answer is:
hot potato
'tough issue to handle' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for hot potato that I've seen before include "Top hat too (anag)" , "Spot" , "taken with pinch of salt?" , "Tricky situation - baked spud" , "Tricky problem" .)
