Actually Britain doesn't hold any importance in Indian minds or any significant power in the world except themselves what actually makes them frustrated. Their sense of self importance doesn't match with their ground realities. For them, they "created" countries like US and India and somewhat built modern techo industrial landscape of the world (they didn't really invent anything significant, neither 3 centuries ago, nor now either).
Unlike in UK where India is, "v civilized em, v controled em", England is a forgiven and forgotten enemy in India no one even cares about. And this isn't a recent phenomenon, UK has lost relevance in Indian affairs long ago. Congress only passed on lip jobs about cooperating with Brits but never truly cared about them, BJP even more openly snubs and ignore UK until Boris took some pro India positions.
Communist PM IK Gujral even called UK "a third rate power not even worth cultivating" which made entire British media cry like b*ches.
