Zara Tindall pictured beaming just days after £30m empire revealed

The inspection took place in front of the ground jury and the veterinary delegate.

Zara beamed during today's outing amid the pleasant September weather.

Her outing comes just days after her £30m empire with her husband, Mike Tindall, was revealed.

The couple, who are not working members of the Royal Family, have built the empire through brand partnerships and deals.

Queen Elizabeth II’s eldest granddaughter is estimated to have earned about £15m from her business interests, while her husband is believed to be Britain's fourth highest-earning former rugby international.

Some of the brand deals include Land Rover, Rolex, Samsung and investment house Artemis.

Zara is also said to have earned £500,000 from her long association with sportswear brand Musto.

While competing at the Burghley Horse Trials earlier this month, Zara met her commercial obligations by launching a new line of winter coats for one of her array of sponsors.

At the event for Musto and Fairfax & Favor, she said of the £400 coats: "I’m safe in the knowledge that I’ll stay warm and dry when it inevitably rains."

During today's outing at Blenheim Palace in Oxfordshire, Zara gleamed in a £295 navy top and £145 trainers, both from Fairfax & Favor.

Meanwhile, Mike Tindall has amassed millions through multiple ventures including his appearance on I’m A Celebrity… Get Me Out of Here, where he finished fourth in the 2022 series.

Zara is represented by Sports & Entertainment Ltd (SEL), an Australia-based talent agency.

She also has had a deal as a brand ambassador for Land Rover, said to be worth £200,000 a year, since 2006.

The mother-of-three has also became a "testimonee" for watch brand Rolex in 2006, with an estimated annual return of £100,000.
