Prince Harry criticises charities 'that are built around egos' Ten years down the line we have made a couple of mistakes and in turn learned from our mistakes. The great thing about Lesotho is that because it's so small, you know that if you're doing it wrong, it's highly visible. And if you're doing it right, you start to see the change. It was a case of Lesotho being quite a hard sell for a lot of people, a very small country that no one knows about, surrounded by South Africa, a landlocked country and I think that combined with us thinking that we knew what we were doing, it evolved and it changed for the better. Sentebale, which means Forget Me Not in the local language of Lesotho, was criticised when its first accounts were published in 2008, showing only £84,000 spent on projects in Lesotho despite more than £1 million raised. High set-up costs were blamed and by 2010 £1.3m of £2m raised that year was being spent on the ground in Lesotho. The Prince said: "There are so many charities that are, dare I say it, built around egos. A lot of charities survive on those egos. But from my point of view and from us at the foundation, being in that position we have the opportunity to bring so many people that are doing great things together to improve things quicker, rather than waiting five years. It's been an emotional rollercoaster but we've come out on top and all I've ever wanted to do was raise enough money to make a difference for Lesotho. The charity has built a residential centre where children and young people come together to talk about their problems, often for the first time, and where they are shown that being born HIV positive should have no stigma attached and no longer means a death sentence. The Prince hopes to expand into other countries such as Botswana, Mozambique and Malawi. Among the celebrities who turned out for the polo match was the former Spice Girl Geri Halliwell, out in public with her fiancé Christian Horner, the Red Bull Formula 1 boss, for the first time since they announced their engagement last week. Halliwell said: "I have met Prince Harry a few times. I've seen him since he was about ten. I have seen him grow up. It is brilliant what he is doing with his life. The Prince was also introduced to Dan Stevens, the former Downton Abbey actor, who was attending as a guest of the main sponsor, Royal Salute whisky, and the former racing driver Sir Jackie Stewart, who, like the Prince, will be at Sunday's F1 race in Abu Dhabi to see Lewis Hamilton try to clinch his second world title. Earlier in the day the Prince finished his brief tour of Oman with a visit to the Sultan Qaboos Grand Mosque in Muscat, which is one of the world's largest, with space for 20,000 worshippers.
