Duke of Westminster and Olivia Henson marry in high-society wedding attended by Prince William

On the morning of the wedding, the Grade I-listed cathedral looked absolutely spectacular, with the main doors adorned with a floral arch. The flowers on display inside the cathedral included rambling roses, philadelphus, campanula, and orlaya grandiflora, as well as birch trees. 

Following the wedding, the trees will be replanted at Hugh's family home, Eaton Hall, while the flowers will be repurposed and distributed to local organisations.

The bride and groom chose flowers from local growers through the 'Flowers from the Farm' network, which champions artisan growers. Many of the flowers seen also came from the Grosvenor's Eaton Estate.

Crowds started to form early on Friday morning, with well-wishers hoping to catch a glimpse of the well-heeled guests, the bride and groom, and Prince William.

Ahead of the wedding, Hugh, 33, acknowledged the interest in his big day, telling Town & Country: "I also just wanted to make it very clear how unbelievably helpful people have been, how supportive they've been so far which I'm unbelievably grateful for. 

"Because I do realise that it's going to be a big thing for the city. It's going to be certainly a huge thing for us, so we're just really grateful for all the help."

Looking smart in a morning suit, William was spotted arriving at Chester Cathedral with the rest of the ushers in a Mercedes van. They were dropped off at a side entrance.

William is the only senior royal in attendance, despite rumours that his ten-year-old son Prince George, the groom's godson, would act as one of Hugh's pageboys.

His wife Kate is undergoing preventative treatment for cancer and has not been seen publicly on a high-profile outing since Christmas Day 2023.

Meanwhile, William's father King Charles, who is Hugh's godfather, and wife Queen Camilla were also a no-show.

William's cousin Princess Eugenie was previously not reported to be attending the wedding, although she had been spotted in Chester enjoying pre-wedding drinks with other guests on Thursday night.

Making an appearance at around 11am with her friend and former Vogue editor Violet Henderson-Vestey, the mother-of-two looked delightful in an olive green number by Joseph and a cream fascinator by Emily London Millinery.

She accessorized with an Anya Hindmarch clutch and wore nude suede pumps by Aquazzura.

Prince Harry's childhood friend Charlie van Straubenzee and his wife Daisy were among the guests pictured arriving.

Prince William's good friend Thomas van Straubenzee and his wife Lucy also made up the guest list. 

Thomas is one of Princess Charlotte's godfathers, while Lucy taught Charlotte and George at their previous London school, Thomas's Battersea.

Another of Prince William and Prince Harry's close friends, Charlie Gilkes, and his wife Anneke, travelled to Chester for the high-society wedding.

Prince William's close friend Edward van Cutsem was spotted arriving with another guest. 

Edward is married to the groom's sister Lady Tamara Grosvenor; the couple also chose to say "I do" at Chester Cathedral 20 years ago.

The groom and his best men rocked up at the cathedral in a green Land Rover Defender.

Looking just a little nervous, Hugh was met with cheers and applause as he arrived at Chester Cathedral at around 11:15am. He smiled and waved to the crowds of well-wishers.

The groom was welcomed by The Very Revd Dr Tim Stratford, the Dean of Chester, who conducted the ceremony.

The Right Revd Mark Tanner preached, while Revd Canon Rosie Woodall led the prayers.

Speaking exclusively to HELLO! on the eve of the wedding, the Dean shared the significance of holding the wedding at the Duke's family church, highlighting Chester as a place the bride Olivia "has fallen in love with". He also expressed his pride in the couple for choosing this special venue for their wedding.

Members of the Grosvenor family who were spotted filing into the cathedral included the groom's mother, Natalia, Duchess of Westminster, who was widowed in 2016 when her husband Gerald Grosvenor, 6^th Duke of Westminster, died unexpectedly of a heart attack.

Natalia looked pretty in pink, matching her daughter Lady Edwina.

Natalia was flanked by her three daughters and Hugh's sisters, Lady Tamara, Lady Edwina, and Lady Viola, who all waved to the crowds before heading in for the ceremony.

Hugh van Cutsem, a friend of the royals, was on hand to greet the groom's family as they arrived. 

Hugh's daughter Grace famously acted as a bridesmaid at William and Kate's royal wedding in 2011, while his late father, Hugh van Cutsem Sr., was King Charles' best friend from Cambridge.

Shortly before noon, blushing bride Olivia arrived at the cathedral with her father Rupert Henson.

They were chauffeured in a vintage Bentley, provided by the Heritage Collection of Bentley Motors in Crewe. The car was originally made for W.O. Bentley, the founder of Bentley Motors, in 1930.

Olivia, 31, looked absolutely exquisite in a wedding dress and veil designed by London-based Emma Victoria Payne. 

The bespoke embroidery design on her gown and veil was hand drawn and reimagined by the designer, incorporating floral motifs and edgings from Olivia's great-great-grandmother's veil from around 1880.

Much had been said about which tiara Olivia would wear on her wedding day. 

She accessorized with the Faberge Myrtle Leaf Tiara made specifically for Grosvenor brides to wear at their nuptials. The tiara has been in the Grosvenor family since its creation in 1906.

She carried a bouquet of flowers, picked from the Eaton Hall gardens, comprising Meadow grass, Ox eye daisies, Iris, Rose, Clematis, Mock orange, Scabious, Sweet pea, Astrantia, Martagon lily and Love in a mist.

Designer Emma Victoria Payne was on hand to make sure the bride was picture-perfect for her grand entrance.

The bride gave one last wave to the crowds before entering the cathedral.

How beautiful did Olivia look on her big day?

After about an hour, the bride and groom emerged from the ceremony and happily waved to crowds.

Hugh and Olivia gave the crowds what they wanted, sealing their love with a kiss.

The bride even joked about the strong winds, saying she was going to "take off".

They looking blissfully happy as they were greeted with whoops and cheers from the public.

Another wave to the crowds before they headed to their wedding car.

Olivia couldn't stop smiling on her big day.

Prince William was seen smiling as he left the cathedral. 

One onlooker cried out, "Best wishes to Kate," referencing the Prince's wife, to which he replied "Thank you" and waved.

The future King happily mingled with other guests after the service.

He was spotted chatting to his good friend William van Cutsem, who is another of Prince George's godfathers, and William's wife Rosie van Cutsem.

His cousin Princess Eugenie, who attended without her husband Jack Brooksbank, was all smiles after the ceremony.

The groom's aunt Leonora Anson, Countess of Lichfield was pictured holding an order of service as she exited the cathedral.

Hugh's sisters Lady Edwina (in pink) and Lady Viola (in red), as well as Edwina's presenter and historian husband Dan Snow, mingled outside the cathedral.

A closer look at Lady Edwina's gorgeous wedding attire, which consisted of a Roksanda Ilincic dress and Malone souliers pointed toe mules.

Hugh's sister Lady Viola, wearing a Selected Femme off-the-shoulder maxi dress and Aquazurra pumps and carrying a Fendi bag, was pictured with her husband Angus Roberts.

The bride's parents Caroline and Rupert were also seen chatting to the groom's mother, Natalia.

Hugh and Olivia were chauffeured away in the Bentley Motors 1930 8-Litre.

The wedding reception is taking place at Eaton Hall, the Grosvenor family's ancestral seat, which Hugh inherited when his father Gerald passed away eight years ago. 

Hugh is the richest man in the UK under the age of 40, boasting a fortune of £10.1 billion, making him far wealthier than his friend William and his godfather King Charles. 

He amassed his wealth – his title, the family home Eaton Hall, and control of the historic Grosvenor Estate – aged 25. His property company, Grosvenor Group, of which he is Chair, owns about 300 acres of land in London's most affluent areas, Mayfair and Belgravia, as well as major city centre developments such as Liverpool's ONE shopping centre.

The Duke is also Chair of the Westminster Foundation, a charitable organisation that focuses on helping vulnerable youth and their families.

Olivia's father Rupert Henson and Hugh's mother Natalia waved off the happily couple as they headed for the reception.

The roughly 400 guests in attendance were whisked off in minibuses for the reception at Eaton Hall.
