Royal brothers Prince William and Prince Harry both played a key role on each other’s wedding day – even if it did mean breaking a few royal rules along the way.

When Prince William married Kate Middleton on April 29, 2011, his younger brother, Prince Harry was standing by his side.
Harry stood proudly as William’s best man, a went against tradition to do so.
Traditionally, the royals don’t have best men alongside them on their wedding days, but instead have “supporters”, as reported by Hello! magazine.
However William wanted to do things differently, and decided to ditch the custom followed by his father and all his older relatives and appoint Prince Harry as his best man.
According to The Times, William would not have married without Harry by his side, as the brothers had been through so much together.
Calling his brother best man, “had more relevance to his life than the alternative”, The Times wrote.
After being appointed best man, Prince Harry was said to be “delighted” with his brother’s choice.
Speaking in 2011, Harry said: “It means I get a sister, which I have always wanted.”
When it came to his own marriage to Meghan Markle on May 19, 2018, Harry asked William to return the favour, and stand as his best man rather than supporter.
While Prince Charles also had his younger brothers Prince Andrew and Prince Edward involved in his wedding day, they were called supporters rather than best men.
