Britain's Prince Harry revealed he was "bricking it" during his first Royal tour abroad.

The 31-year-old prince opened up about feeling "incredibly nervous" when he was asked to represent his grandmother, Queen Elizabeth II, on an official engagement overseas for the first time in 2012 on a visit to the Bahamas and Jamaica.

Speaking during a BBC documentary to mark the monarch's 90th birthday titled 'Elizabeth at 90 - A Family Tribute' which aired on Thursday (21.04.16), he shared: "When you go on official tours, to Bahamas, Belize, and all those places, on my first proper tour, representing her, I was bricking it, I was incredibly nervous, you know, would everyone be disappointed that it wasn't her? Will I get it all right? Will I make any mistakes? So you know there is a huge amount of pressure."

However, the flame-haired monarch - who is fourth in line to the throne - was allowed to "crack on" with the job at hand and relied on the lessons he had learned through watching his grandmother over the years.

Prince Harry continued: "But you know, she has led the way. And I think she is more happy to let you crack on. If you get it wrong, then she'll tell you. And likewise if we get it wrong, then we apologise."
