Soldier, in consequence, left umbrella (7)
I believe the answer is:
parasol
'umbrella' is the definition.
(I know that parasol is a type of umbrella)
'soldier in consequence left' is the wordplay.
'soldier' becomes 'para' (short for paratrouper).
'in consequence' becomes 'so' ('so' can mean consequently).
'left' becomes 'l' (common abbreviation).
'para'+'so'+'l'='PARASOL'
(Other definitions for parasol that I've seen before include "cover" , "sunblock" , "Protection from sun" , "Fair-weather umbrella" , "mushroom" .)
