He continued, “The fact that the press does not follow their every move is welcome.
“There is certainly not the interest there is in the Queen, Charles, Camilla, William and Kate.
“I don’t think they would want that, I think they just want to be able to fulfill their royal duties and commitments.

Mr Fitzwilliams also told Express.co.uk that the Wessexes are “closely following in the footsteps” of Princess Anne.
He spoke of the inspiration Sophie gets from her sister-in-law’s role as a working royal, highlighting the Princess Royal’s no-frills approach to engagements.
He said of Anne: “I think over the decades the public has respected her work ethic enormously.
“That’s basically what people expect from her, and that’s what she does.
“The Wessex are following the same footsteps. The Wessexes and Princess Anne are examples of monarchy at its best. “
