Prince William, who was the groom's usher, is understood to have witnessed the disruption.
Just Stop Oil (JSO) protesters have attempted to interrupt the departure of the Duke and Duchess of Westminster following their wedding at Chester Cathedral.
The newlyweds made their way outside while waving to the applauding crowds, where they shared a kiss.
However, they were soon stopped by two JSO protesters who used fire extinguishers to let off their signature orange smoke.

One of the women was heard shouting “Just Stop Oil” as the device was released.
The two female protesters were booed by the crowd before they were restrained and then taken away by the police.
JSO has confirmed that they are responsible for the disruption. The two women involved released statements ahead of the disruption.
One said: "Weddings are a time of coming together in celebration to make a commitment to the future. However, for countless millions around the world there is no future unless we come together to stop oil and gas. That’s why we are demanding that the next UK government work with other countries to phase out fossil fuels by 2030.”
The second added: “What do we value most? The wealth of billionaires like the Duke of Westminster OR the lives of the billions who are being destroyed by the fossil fuel industry? Extreme wealth and the climate crisis are both symptoms of a broken system that is not serving most ordinary people.”
“I am asking my fellow citizens to peacefully, but determinedly, demand an emergency plan to stop the drilling and burning of oil, gas and coal by 2030. My grandchildren, all our children and all future generations’ lives are dependent on what we all do right now.”

PACrowds carried on cheering for the couple in order to drown out the booing of the protesters' actions.
The groom arrived in a dark green Land Rover Defender with his three best men, long-standing best friends of the duke, in tow.
The bride arrived in a bespoke gown and veil designed by Emma Victoria Payne, a British bridal designer.
The dress and veil had links to her ancestry via detailed embroidery that was reminiscent of her great great grandmother’s attire, incorporating floral motifs as found on the original from the 1880s.
Prince William, who is playing a crucial role in the wedding, arrived at the cathedral ahead of the nuptials. Neither his wife, Princess Kate, nor his three children, accompanied him to the event.

Around 400 guests, including Princess Eugenie, were brought to the venue by coaches.
Chester has been decorated with 100,000 flowers paid for by the Duke, who has topped the Sunday Times 40 Under 40 Rich List. Following the ceremony, they will now be donated to local charities.
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, joined by a group of musicians from North West England.
Residents of Chester were offered free ice creams in honour of the special event, with the couple teaming up with three independent businesses to provide the sweet treats.
Ahead of the ceremony, a spokesperson for the couple released the following statement: “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.”
