Author, broadcaster and etiquette coach William Hanson explores why there’s such a demand for British politesse around the world.

We joined William at the Wasan Knowledge Hub in Mumbai where he teaches classes in business protocol and social etiquette. William asks Ekta Wasan why she set up the academy two years ago, and students explain why they have a desire to learn these very British skills.

Then to Shanghai, another city where William’s knowledge is craved. Three years ago, Chinese men and women had no idea what etiquette training was. So why the sudden demand?
