Thousands lined the streets of Chester for the wedding of the Duke of Westminster, where the Prince of Wales acted as an usher.

Two women were removed from the crowd by police after orange smoke was deployed from a fire extinguisher-type device as the billionaire aristocrat, 33, and his new bride Olivia Henson, 31, left Chester Cathedral after the service with the wedding party, including William as an usher.

One of the women was heard to say “Just Stop Oil” as the device was released, after the couple kissed for the crowds.

William, a close friend of duke Hugh Grosvenor, who studied at Ellesmere College in north Shropshire, went through a side entrance of Chester Cathedral, out of the view of many of the crowds on Friday morning, ahead of the ceremony at midday.

Members of the public began arriving outside the cathedral to catch a glimpse of the event from early in the morning, bringing camping chairs and picnics.

The bride’s veil, designed by Emma Victoria Payne and featuring an embroidery design which incorporated floral motifs from Ms Henson’s great-great-grandmother’s veil from around 1880, blew in the wind as she arrived at the cathedral to the cheers of the public.

Her dress was made by the same designer and she accessorised with blue shoes and the Faberge Myrtle Leaf Tiara made for Grosvenor brides to wear on their wedding day, which has been in the family since 1906.

She arrived with her father in a vintage Bentley, originally made for the car manufacturer’s founder in 1930, while the groom arrived in a green Land Rover Defender.

Around 400 guests, including Princess Eugenie, were brought to the venue in coaches.

The Duke of Sussex was not there after it was mutually agreed he would not attend, amid a long-running rift with his brother.

Guests did not include the King, the groom’s godfather, the Queen or the Princess of Wales, who has been out of the spotlight as she undergoes treatment for cancer.

The Duke of Westminster is godfather to William’s son, Prince George, and also, reportedly, to Harry’s son Prince Archie.

The wedding was officiated by the Dean of Chester, the Very Revd Dr Tim Stratford and the service was sung by the Chester Cathedral Choir, accompanied by a group of musicians from North West England.

The people of Chester were offered free ice creams in honour of the occasion, after the couple teamed up with three independent businesses to provide the treats.

The Duke of Westminster topped The Sunday Times 40 Under 40 Rich List earlier this year, boasting a fortune of £10.1 billion.

His bride, who grew up in London and Oxfordshire, has worked in the sustainable food and drinks industry, most recently at London-based artisanal food company Belazu.

The couple are said to have chosen the wedding venue for its beauty and because of the personal connection to the duke, whose family home Eaton Hall is nearby.

William and Harry were both ushers at the wedding of his sister Lady Tamara Grosvenor at the cathedral in 2004.

A spokesman for the duke and Ms Henson said: “This is an incredibly special day for the Duke and Miss Henson and they are very much looking forward to the service.

“It means a lot to them to marry in Chester Cathedral, especially given the Grosvenor family’s long and close personal connection to both the Cathedral and the city of Chester.

“The couple have also been moved by the messages of support they have received from around the region and are hugely grateful that people want to share in their happiness.”

The spokesperson added: “The Duke and Miss Henson have taken a great deal of care in planning the wedding, putting their own personal stamp on all the arrangements and have made a conscious effort to involve local and regional suppliers in several aspects of the day.”

Seasonal flowers for the ceremony were sourced from local growers and will be made into bouquets after the wedding, to be delivered to local charities, churches and organisations.

The couple announced their engagement in April last year after being together for two years.

The Duke of Westminster became an instant billionaire when he inherited his title and control of the historic Grosvenor Estate aged 25, following the death of his father from a heart attack in 2016.

His property company, Grosvenor Group, owns about 300 acres of land in Mayfair and Belgravia, as well as major city centre developments such as Liverpool’s One shopping centre.
