Prince Harry has inherited an estimated £9m from his mother’s estate after he turned 25 years old today.

Although he will not get access to the full amount, he will be able to receive £300,000 worth of interest each year from the money left by Princess Diana.

But despite becoming a multi-millionaire, Harry will not be celebrating his birthday in the usual style.

Prince Harry will be making his first-ever formal visit to the United States later this month to participate in the second annual Veuve Clicquot Manhattan Polo Classic, taking place on Saturday, May 30th.

The Veuve Clicquot Manhattan Polo Classic will coincide with the 400th anniversary of New York and opening day of the Governors Island season.

Event proceeds will benefit American Friends of Sentebale, a U.S.-based charity that supports at-risk children in Lesotho, Africa.
