As we probably don't need to tell anyone who visits this page on regular basis PRINCE HARRY IS LANDING IN WASHINGTON LATER TODAY!!!

Yes, the Prince is due to begin a seven-day visit to the United States in just a few hours from now (here's the schedule) and the first port of call is Washington DC where he will be supporting the work of HALO trust, the landmine clearance charity supported by his mother, Diana.

In Washington, he'll support a cause embraced by his late mother - landmines. When Diana called for an international ban, seven months before she died, a Tory minister accused her of being a "loose cannon".

The princess's son has vowed to finish the work of someone, he said, "had more guts than anybody else".

It is his first return to the US since being pictured naked during a game of strip billiards in a Las Vegas hotel.

"I probably let myself down, I let my family down, I let other people down," he said in an interview after that unhappy event. "It was probably a classic example of me probably being too much army, and not enough prince."

This tour will give the Prince the chance to show that he has matured enough to take on a senior role in the royal family, as his grandmother cuts back on her workload.

Ahead of this latest trip, the prince's private secretary said Harry wanted to highlight "once again the extraordinary commitment and sacrifice of our injured servicemen and women - our wounded warriors."

Jamie Lowther-Pinkerton said: "Although a prince, Harry is also an operational soldier - indeed he's a soldier's soldier - therefore throughout this briefing the recurring theme is to help recognise and bring a spotlight on to the work being done to help these outstanding young men and women."

In Washington, the prince will visit Capitol Hill and view a photography exhibition staged by the anti-landmine organisation the Halo Trust.

Harry will be escorted around the display by Senator John McCain.

We'll be posting pics of Harry's trip as soon as they drop!
