Hugh Grosvenor, the Duke of Westminster - a childhood friend of Prince Harry and Prince William - will marry Olivia Henson on June 7 in what will be one of the key social events of the season, but only one brother will attend . An insider source has revealed why. Speaking to People magazine , a friend close to the Duke of Sussex opened up about Harry’s decision not to attend the upcoming wedding of Prince Archie ’s godfather, claiming there is no bad blood.

Noting it was an “understanding between the two friends”, the source told the news outlet that the pair agreed it would be difficult for the Californian-based royal to attend the wedding due to his estrangement from the royal family and particularly his brother, William who will also attend the wedding. The source claimed the decision was a mutual agreement between the two dukes and that Harry sends “his love, support, and admiration for the couple” on their special day. It comes after a source spoke to the UK’s Times , claiming the reason why is because Grosvenor did not invite Harry and Meghan Markle as he reportedly decided the brothers’ falling out could overshadow the big day.

Meanwhile, William will reportedly serve as an usher on the special day. His duties include welcoming guests and helping them find their place at the Chester Cathedral in northern England, this Friday local time. Grosvenor is clearly a valued friend to the brothers and as well as being godfather to Archie, 5, he is also godfather.
