Composure of model touring India (5)
I believe the answer is:
poise
'composure' is the definition.
(I know that poise is a type of composure)
'model touring india' is the wordplay.
'model' becomes 'pose' (model can mean to pose).
'touring' is an insertion indicator (touring can mean going round).
'india' becomes 'i' (phonetic alphabet: alpha, bravo, charlie etc.).
'pose' enclosing 'i' is 'POISE'.
'of' is the link.
(Other definitions for poise that I've seen before include "Self-confidence" , "Dignity and assurance of manner" , "Graceful and elegant bearing in a person" , "Physical balance" , "cool" .)
