Harry At 30 (ITV, 8pm)

MOST of us aren't wild about Harry, but those without anything worth watching on saved shows may well be tempted into catching this tribute to the Prince, who turns 30 on September 15. Prince Henry of Wales, to give him his official title, has grown up in front of the cameras, and while there may be some photographs he'd rather forget, he's gone on to become one of the most popular members of the royal family.

The documentary follows his path from mischievous youngster to royal soldier and, although we’re unlikely to hear too much from the man himself, there will be Ingrid Seward of Majesty Magazine, and the Evening Standard's royal editor Robert Jobson to offer plenty of tittle-tattle.

"I remember once he had a pop at me because I'd written a story about him. But I quite admire him for that, he will stand up for his position he won't just smooth it over – he will say what he wants to say and then that will be it," says Jobson.

We’ll relive the moment he lost his mother in 1997, when he was still 13. Former press officer to the Queen, Dickie Arbiter, talks about the devastating impact of her death, and the programme also explores how Harry has found his own way to continue her legacy by working with disadvantaged children and issues around HIV and Aids in Africa, and helping to set up the charity Sentebale.

Former army chief Lord Richard Dannatt talks about the difficulties involved in sending an heir to the throne to a combat zone in 2007, while press photographer John Stillwell remembers how the prince defied the cynics.

"Other photographers before I went were all saying to me exactly the same thing – Harry will be in Camp Bastion in a 30ft deep bunker, he won't even see daylight, and it wasn't like that at all. It was probably the worst conditions that I've seen. It was a bombed out college on the front line," says Lord Dannatt.

Injured former servicemen Ben McBean and Jaco Van Gass also talk about Harry's desire to be treated like any other soldier, and there's a look at his latest project, The Invictus Games, a brand new Olympic-style event for wounded soldiers.

Having been spoofed on TV so badly, we now know that Harry is one of most eligible bachelors on the planet. OK magazine's royal editor Chrissie Reeves, journalist and writer Celia Walden and Harry's friend Joss Stone speculate on the woman who could convince the prince to take a leaf out of his brother William's book and settle down.
