The Prince of Wales is to make an official visit to India and Oman later this month.
It will be Charles' fifth trip to India
Charles' last trip to India - in 1992 - provided one of most enduring images during the breakdown of his marriage to Diana, the late Princess of Wales.
Diana memorably posed alone for photographers in front of the Taj Mahal, the famous monument to love which, 12 years earlier, Charles had promised he would take her to see.
The couple announced their separation a few months later.
There had been reports that on this trip Charles would be accompanied by his partner, Camilla Parker Bowles, but Clarence House confirmed that this was not the case.
In what will be his longest foreign trip for some time, the prince will spend nine days in India where he will watch the making of a Bollywood film.
He will also visit projects in both rural areas and cities highlighting work on conservation, restoration, youth entrepreneurship, and sustainable development.
The prince, who begins his tour on 28 October, first travelled to India in his twenties in 1975. This will be his fifth visit.
He met Mother Teresa in India in 1980 and in 1991 he represented the Queen at the funeral of Rajiv Gandhi in Delhi.
A Clarence House spokesman said: "The Prince is very much looking forward to going to both India and Oman for which he has a great affection."
The prince will be in Oman for four days during Ramadan, the Muslim month of fasting, and also for Remembrance Sunday on 9 November.
Charles, whose last visit to the country was in 1999, is a close friend of
Sultan Qaboos who was educated in the UK.
