The Duke of Sussex has assumed wedding duties once again – this time attending the nuptials of his childhood friend as best man.
The Duchess of Sussex, celebrating her 37th birthday on Saturday, attended separately and waved to crowds of well-wishers as she entered.
Mr van Straubenzee, who works for investment management firm Brown Advisory, is marrying party and wedding videographer Daisy Jenks.
The groom played a major part in Harry’s wedding in May as an usher, along with his older brother, Thomas, and was said to have roasted the royal in a humorous reception speech.
Charlie’s older brother, Thomas, is close friends with the Duke of Cambridge and is godfather to Princess Charlotte, three.
Guests clad in summery outfits and morning coats began filing into the church as wedding bells rang one hour before the ceremony began.
The bride arrived in a vintage car shortly before 3.30pm.
Hymns including Shine Jesus Shine and Lord Of All Hopefulness could be heard from outside.
