Prince William set to be an usher on the Duke of Westminster’s wedding ceremony

It’s set to be the society event of the summer, with so many members of the aristocracy in attendance that it’s been dubbed the ‘almost royal wedding’.

But one question has been the talk of the town for months – why Prince Harry may have turned down an invitation from his old friend Hugh Grosvenor, the Duke of Westminster, for his June 7 nuptials.

Now friends of the Royal Family think they have solved the mystery, claiming that Prince Harry refused to attend when he discovered his brother William had been given a prominent role.

Last night the Sunday Times reported that the Prince of Wales will be an usher at the duke’s wedding to Olivia Henson.

The Mail on Sunday understands that his son Prince George is set have a prominent role too, as he is the duke’s godson. The attendance of King Charles, who is the duke’s godfather, is yet to be confirmed.

Known as ‘Huey’ to friends, the 33-year-old duke is one of very few to remain close friends with both William and Harry.

Friends have suggested the Prince of Wales was first asked in December to be an usher at the wedding at Chester Cathedral next month. At one stage, he was even said to have been earmarked as a best man.

Harry was said to have been ‘put out’ by the news because he had always regarded himself as being closer to the duke – who is also godfather to the Sussexes’ first-born, Prince Archie.

Last night, a well-informed source told The Mail on Sunday: ‘William was asked to have a prominent role in the wedding and that’s what triggered Harry to decline an invitation. Apparently he [Harry] was put out by the request when he thought it should have been him.’

Referencing the lack of public details about the occasion, the source added: ‘Both the Palace and Hugh’s people decided to hold dear the operational part of the wedding once the leak about Harry not attending made the papers.’

Last year, it was claimed that Prince Harry had been ‘snubbed’ from the wedding, but a source close to the Sussexes was at pains to explain to US publication Page Six that both Meghan and Harry had in fact received invitations, but had jointly decided to decline.

Neither Harry nor his wife Meghan Markle will attend the wedding, which is expected to have 400 guests, despite Grosvenor being so close to Harry that he is a godfather to the couple’s five-year-old son Prince Archie. 

Prince William will be among the groom’s party, but the Princess of Wales, who is receiving cancer treatment, is not expected to attend.

Grosvenor, known as ‘Hughie’ to his friends, and Henson, were introduced by mutual friends in 2021.

The couple have insisted on a ‘strictly no-gifts policy’ for their guests, according to The Sunday Times.

The Duke inherited his £9.3billion fortune when his father Gerald Grosvenor suffered a sudden heart attack while out on a country walk and died aged 64 in 2016. 

He inherited 300 acres across the affluent London areas of Mayfair and Belgravia, as well as estates in Oxford, Scotland and properties around the globe. This includes his current residence at Eaton Hall, the 10,872-acre family estate.

After the wedding service at Chester Cathedral, guests will then enjoy a grand reception at nearby Eaton Hall. 

The following day they will host a second, smaller reception at Eaton Hall for close family and friends, but further details of both receptions are being kept secret. 

However it is understood that the King, who is Grosvenor’s godfather, will not attend the wedding. He is still undergoing cancer treatment and will be travelling to France the day before the ceremony with the Queen and Prince William to commemorate the 80th anniversary of the D-Day landings in Normandy.

Sustainability will be a key feature of the wedding, with all food, flowers and products used for the wedding locally sourced where possible. 

The city of Chester is also bracing itself for the celebrations, with thousands of people expected to line the streets. 

Some shops, restaurants and cafés near the cathedral will be closed on the day for access and security. 

A spokesman for Kensington Palace said the Prince of Wales is attending the wedding in a private capacity, and said it does not comment on events during his private time.

A representative for Prince Harry was also contacted for comment. 

Earlier this month, the engaged couple visited several local charities in Chester helped by the Westminster Foundation – showcasing their charisma and drawing comparisons from the Prince and Princess of Wales.

Grosvenor, who is known to be publicity-shy and has always maintained a low profile despite his extreme wealth, is known to be ‘incredibly excited’ but ‘nervous’ about the wedding.

Olivia and Hugh announced their engagement on April 23, 2023, after two years of dating. 

Raised at Eaton Hall, Cheshire, Hugh Grosvenor was privately educated at Ellesmere College before obtaining a BSc in Countryside Management from Newcastle University.

After his graduation, Grosvenor worked in estate management at the food and agriculture company Wheatsheaf Group, an investment business based in the Eaton estate and owned by the Grosvenor Group.

Afterwards, he held an account manager position at sustainability company bio-bean, which turns coffee-related waste into bioproducts such as biofuels and logs. 

The future Duchess of Westminster also comes from a wealthy background. Olivia descends from the Hoare banking family as well as the Marquesses of Bristol and the Dukes of Rutland, according to the Telegraph.

The outlet also says her uncle is the Grand Master of Scottish freemasons and her father is stockbroker Rupert Henson.

Olivia reportedly also has a 29-year-old brother who works in asset management and a 26-year-old sister who’s in a brand relationships role.

She is also said to speak Spanish and Italian after completing a Hispanic Studies and Italian degree at Trinity College in Dublin.

Much like the Princess of Wales, Olivia is understood to have attended the elite Marlborough College, and before that was at the equally revered Dragon School in Oxford along with fellow alum Emma Watson.

She worked at Daily Dose LDN and No1 Rosemary Water before landing a role at Belazu – a B Corp ingredients brand – where she is currently a Key Account Manager, in 2019. 

Close friends with the Prince and Princess of Wales, the Duke is the youngest of Prince George’s godparents.

He has previously represented the country at Olympic Skeet Shooting competitions both internationally and in the UK.

Hugh previously dated property and recruitment consultant Harriet Tomlinson, but the couple, who met at £6,000-a-term day school Ellesmere College in Shropshire, split in 2020.

The Duke also supports the rehabilitation of wounded or injured members of the Armed Forces and donated £2.5million to the Health Service when the COVID-19 pandemic broke out, but said he was so ‘humbled’ by the work of doctors and nurses he wanted to give another £10million.
