Prince Harry will be in New York on Monday to deliver a keynote address at a UN

General Assembly meeting for Nelson Mandela Day.

The event begins at 10am EST, with the Duke delivering his remarks around 10:30am.

Harry's supporters see his presence at the event as a sign of his rise on  the global

stage in contrast to claims in the British tabloids that he would lose importance after stepping down from his royal duties

According to a statement, the General Assembly will hold an informal meeting to

mark the observance of "Nelson Mandela International Day", during which the

2020 UN Nelson Mandela Prize will be awarded to Mrs. Marianna V. Vardinoyannis

of Greece and Dr. Morissanda Kouyaté of Guinea. The Deputy Secretary-General

and the President of the General Assembly will deliver remarks at this event.
