OTRC: Prince William turns 30, set to inherit $15.7 million on birthday

Prince William, the second in line to the British throne, turned 30 on Thursday, June 21, and will therefore receive about $15.7 million inherited from his late mother, Princess Diana.

According to Hello! magazine and other outlets, her will called for the bulk of her estate to be held in a trust for William and his younger brother Harry and then given to them when they turned 25. After she died in 1997, executors changed the inheritance age to 30, the outlet says.

Diana left in her will a net estate of about 12.9 million pounds sterling after an inheritance tax of some 8.5 pounds was deducted, the reports say. The UK newspaper The Guardian says the sum is made up of "stocks and shares and jewellery, dresses, other personal belongings and cash" from a 17 million pounds sterling divorce settlement from William's father, Prince Charles.

"With shrewd investment, some commentators have estimated the estate could now be worth around 20 million - half for William, and half for his brother when he reaches 30 in September 2014," the newspaper said.

William, formally known as the United Kingdom's Duke of Cambridge, is currently staying with his father at his and wife Camilla's home in Highgrove. The younger prince plans to mark his birthday "in a low-key, private fashion," a St. James's Palace spokesperson told the UK Newspaper The Daily Mail.

William was born at 9:03 p.m. on June 21, 1982. Scores of people filled the streets outside the hospital where Diana gave birth to celebrate the birth of the boy who was set to one day become king.

The sandy-haired prince, who resembles his mother, soon became a heartthrob in his native UK and in many other countries. In July 1995, he began attending Eton College, studying Geography, Biology and Art History. He took a year off to participate in UK army training exercises in Belize and Chile. He also worked on British dairy farms and visited countries in Africa.

William later enrolled at St. Andrews University in Scotland, studying Geography. He graduated in 2005. During his time at school, he met Kate Middleton. They would go on to date on and off before marrying on April 29, 2011 in a ceremony televised around the world.

The two wed at Westminster Abbey, the site of Diana's funeral. The princess and her boyfriend were killed in a car crash in Paris in August 1997 after being chased by celebrity photographers. She was 36. William and Harry were 15 and 12 years old at the time. Her funeral was also televised and drew a global audience of about 2.5 billion people. She was laid to rest on an island at the Althorp Estate in Northamptonshire, north of London.

Prince William said in an interview with ABC's Katie Couric in May that he is "very sad" Diana will never get the chance to meet his wife Kate, while his brother Harry added that their late mother would have "loved" the duchess and had the "best seat in the house" at the royal couple's 2011 wedding.

After graduating from college, William joined the Royal Military Academy Sandhurst as an Officer Cadet and was commissioned as an army officer in front of his grandmother, Queen Elizabeth II, in December 2006. He joined the Household Cavalry as a Second Lieutenant and the queen appointed him to become a Royal Knight Companion of the Most Noble Order of the Garter in 2008, according to his official website.

William is currently a Search and Rescue Pilot with the Royal Air Force and is based at Anglesey, Wales. The Daily Mail says he has the authority to "command RAF Sea King helicopters during rescue missions."

William also spends his time touring, often with his wife, to promote his charities and taking part in other royal commitments. Earlier this month, he and Kate joined Queen Elizabeth II for events marking her Diamond Jubilee, which celebrates the 86-year-old monarch's 60 years on the British throne.

William, Kate and Harry are also set to attend the 2012 Olympics in London in July as ambassadors to the British Olympic and Paralympic teams.
