Criticise as dilapidated (3,4)
I believe the answer is:
run down
This clue is a double definition.
'criticise' is the first definition.
(I've seen this before)
'dilapidated' is the second definition.
(I've seen this before)
'as' acts as a link.
(Other definitions for run down that I've seen before include "Drained" , "pan?" , "In weakened health" , "exhaust?" , "slightly off" .)
