The Duke and Duchess of Cambridge will go on a tour of India next year, Kensington Palace has announced.
The trip next spring will be the first time William and Kate have visited the country.
It is unlikely they will take Prince George and Princess Charlotte.
News of the royal tour comes as Indian Prime Minister Narendra Modi is on an official visit to Britain which has seen the unveiling of £9 billion (NZ$20.95 billion) of commercial deals between the two countries.
He has been greeted warmly by Prime Minister David Cameron and has had lunch with the Queen at Buckingham Palace.
Modi is the first Indian premier to visit Britain in nearly a decade but he has faced protests over his record as chief minister of Gujarat - including over riots in 2002 where more than 1000 Muslims were said to have died.
William's parents, the Prince of Wales and the late Diana, visited India in February 1992.
Diana was famously photographed sitting on her own on a bench outside the Taj Mahal in a picture that hinted at loneliness and became the defining image of the tour.
The couple separated a few months later.
Prince Charles and his new wife Camilla are currently touring Australia.
