The photograph of a smiling prince on the cover of a gay magazine is a sign of William's willingness to embrace the diverse nature of British society. It's also a reminder that the monarchy is an institution that can evolve.

In the late 1980s, Diana, Princess of Wales, would visit people who had Aids or leprosy. Her former bodyguard, Ken Wharfe, told the Diana inquest that the Queen had asked why the princess didn't get involved "with something more pleasant".

Three decades on, her son is highlighting the work being done against bullying and in support of removing the stigma surrounding mental health.

Another striking aspect of this interview is that William is a future king. As things stand, one day he'll be head of state of the UK and 15 other countries - some of which discriminate against gay people.
