British high society is eagerly anticipating the wedding of the year as the Duke of Westminster, Hugh Grosvenor, 33, and Olivia Henson, 31, prepare to marry on June 7 at Chester Cathedral. This event promises to be lavish, given the Duke’s status as the UK’s wealthiest person under 40.

Crowds are expected to line the streets on the big day just as they did for Hugh's sister's wedding in 2004

Excitement is building, especially among the young couple, who recently visited Chester to tour their wedding venue and meet with local charities. Hugh joked about the upcoming ceremony, adding to the anticipation.

Prince William, 41, a close friend and godfather to the Duke’s godson Prince George, will serve as an usher. The guest list remains largely confidential, but the 400 attendees are expected to include many high-profile figures.

Hugh chose Chester Cathedral for its family significance, having hosted his father’s memorial and his sister’s wedding there. The Duke and Olivia plan to move to Eaton Hall, near where Hugh grew up, transitioning from London to Chester.

Reflecting on the big day, Hugh expressed gratitude for the city’s support, acknowledging the event’s significance for both the couple and Chester. This wedding is reminiscent of Lady Tamara Grosvenor’s 2004 nuptials, which drew large crowds and significant security.

With Prince William’s prominent role confirmed, rumors suggest this may have caused Prince Harry to decline an invitation. Hugh Grosvenor, affectionately known as ‘Huey,’ was named Prince George’s godfather in 2013, and the young prince, now 10, will also play a significant role in the wedding, just before starting secondary school.
