I am a fan of his holiness the Dali Lama, I hope in his lifetime he is able to return to Tibet as it's leader, even if it is just as their spiritual leader.
I was also a great admirer of King Hussein of Jordan, his philanthropic work was not confined to his own kingdom but there are many children who he paid for an education here in the UK, it wasn't until after his death that it was made known he was doing this.
Ghandi too was a good leader too, a great ideas man and we have him to thank for such quotes as: "be the change you want to see" and "the measure of a good country and it's people is how it treats it's poor"
