Delhi is 4th of 6 places that changed the world

Midnight on August 14th, 1947, in Delhi. The British pulling out of India was not the first act of decolonisation, but it was the biggest.

Gavin Esler explores what it meant to move into a world without empire. Among those joining him will be Vikram Seth, Niall Ferguson and Sir Sonny Ramphal.
