Fire Tory: identify allowance (13)
I believe the answer is:
conflagration
'fire' is the definition.
(I know that fire can be written as Conflagration)
'tory identify allowance' is the wordplay.
'tory' becomes 'con' (abbreviation for Conservative).
'identify' becomes 'flag' (flag can mean to label or identify something).
'allowance' becomes 'ration' (I've seen this before).
'con'+'flag'+'ration'='CONFLAGRATION'
(Other definitions for conflagration that I've seen before include "result of arson" , "Inferno" , "Great fire" , "Large destructive fire" , "terrible blaze" .)
