The Prince of Wales has arrived in India at the start of a nine-day official visit.
The trip will be Prince Charles' fifth to India
He is leaving behind the acrimonious row between his sons and Paul Burrell over the former butler's book about the late Princess Diana.
The prince's last trip to India was in 1992 with his then wife.
Speculation about their marital troubles was fuelled when the princess was photographed sitting alone in front of a monument to love, the Taj Mahal.
Further tension was noted in Jaipur, where Charles' attempts to kiss Diana at a polo prize-giving ceremony were spurned when she turned her head away.
On this trip the prince will highlight the close links between the UK and India, focusing on heritage and restoration, sustainable development and youth enterprise.
His companion, Camilla Parker Bowles, is not accompanying him on the trip.
Prince Charles will see water conservation projects and restoration work, and meet young entrepreneurs during his stay in the capital Delhi, the northern state of Rajasthan and the city of Mumbai.
In New Delhi, which was built by the British as an imperial capital of India, Charles will visit a shelter for homeless women and children, and a trust he set up to help youngsters succeed in business.
He will also see water conservation projects in two villages in Rajasthan, and restoration work at the Nagaur Fort, which is being part-funded by a UK charity.
He will meet the cast and crew of a new British/Indian Bollywood movie in Mumbai and attend a joint British-Indian naval event on HMS Kent in Mumbai Docks.
Fears for the safety of the Prince will be heightened during his time in Mumbai which was recently targeted in a series of fatal car bombings that killed more than 50 people.
After India, Charles will travel to the Sultanate of Oman, spending four days in the Islamic country.
Charles first visited in 1975, then in 1980 when he met Mother Teresa, and in 1991 when he represented the Queen at the funeral of assassinated prime minister Rajiv Gandhi.
He leaves the day after his ex-wife's former butler, Paul Burrell, published his book revealing details of the princess's private life.
The book - called A Royal Duty - includes extracts of private letters written to and from Diana, as well as claims about her marriage, break-up, subsequent relationships and death.
Before the book was published, Charles' sons William and Harry, expressed hurt at Mr Burrell's revelations.
It is believed a face-to-face between Mr Burrell and William will take place.
Mr Burrell has denied accusations he had let Diana down, insisting his book is a "loving tribute", written after he was the victim of a "rollercoaster of madness".
In an interview with the BBC, Mr Burrell said Princes William and Harry should "grow up", after they accused him of betrayal over the book.
Mr Burrell had said he would like to meet both Prince William and Prince Harry, and William is reported to be keen on the idea of meeting, wanting to express his hurt over the affair as well as ensuring there are no further revelations.
