A Wiltshire businessman was left “stunned” by Queen Camilla during a royal visit to his new state-of-the-art facility.

The Queen visited the Stonegate Farmers site at Lacock Green on Tuesday, September 3, during a trip that also saw her open the Dyson Cancer Centre at the RUH in Bath.

During the visit, Queen Camilla officially opened the firm’s new headquarters, which has been operational for a few months, by unveiling a commemorative plaque.

She also toured the purpose-built facility, which is designed for packing organic and free-range eggs, and spoke to many members of staff.

Chief executive Adrian Gott accompanied the Queen around the site and told this paper he was left surprised by how “down to earth” she was.

He said: “It was amazing, she was so engaging and gave up so much of her time talking to almost every member of staff and showing interest in their roles and jobs.

“I was stunned and amazed at how down to earth she was and how much time she gave all individuals from every facet of the business.

“It was really special and we’re very proud to have hosted her.”

Mr Gott says the royal visit marked an exciting transition for the business after the final touches of the new facility were completed in recent weeks.

He added: “It’s a very special day for us because it’s not every day that the Queen walks through your workplace.

“She was so interested and asked so many questions which was great for the whole team, and really elevated the day.

“It’s important to provide the right facilities for our staff and set a standard where everybody wants to come into work, so it was good to get it completed before her visit.”

Prior to her tour of the Wiltshire egg packing site, the Queen was in Bath where she inaugurated the Dyson Cancer Centre in Bath, following its opening in April.

The centre, which was built following £10 million in donations from thousands of people, centralises most of its cancer services under one roof where up to 300 patients can be treated daily.

During her visit Camilla chatted to Paul Holdway, 55, from Trowbridge, Wiltshire, who was recovering after a stem cell transplant treatment for blood cancer.

He was joined by his wife Nicky Holdway, 55, a nurse, and his parents Sheila and Richard Holdway.
