Jollies around India's border (3)
I believe the answer is:
rim
'border' is the definition.
(I've seen this before)
'jollies around india's' is the wordplay.
'jollies' becomes 'RM' (nickname for the Royal Marines).
'around' means one lot of letters goes inside another.
'india' becomes 'i' (phonetic alphabet: alpha, bravo, charlie etc.).
'rm' enclosing 'i' is 'RIM'.
(Other definitions for rim that I've seen before include "Edge or margin" , "Edge, border" , "Outer edge of a wheel" , "Edge - lip" , "An edge, canyon or cup" .)
