Catherine, Princess of Wales appears to have hinted Queen Elizabeth's fighting spirit helped her through her cancer battle

She was seen changing gears and motoring through the countryside - in footage similar to that shot of the Queen doing the same in her 1992 BBC documentary 'Elizabeth R: A Year in the Life of the Queen'.

A clip that has resurfaced since Catherine released her video shows the monarch, who was then 66, driving through a wood in the Sandringham estate in Norfolk.

The Queen was regularly seen driving around her various royal estates in Land Rovers over the years, and commentators and royal fans have claimed Catherine was obviously channelling and giving a "nod" to the Queen's famous stiff upper lip by posing like Her Majesty in her Land Rover.

Along with announcing she had beaten the cancer with which was she was diagnosed earlier this year, Catherine used her video to show her cosying up to her husband Prince William, 42, and playing with their three children Prince George, 11, Princess Charlotte, nine, and six-year-old Prince Louis.

Her clip has been praised as a "polished" bit of publicity by British PR expert Mark Borkowski.

He told the MailOnline it allowed the Wales family to show their "vulnerability" while "staying in command".

He added: "The Kate film is a groundbreaking moment. The household on the front foot. Let's not forget that they lost control of the cancer narrative by staying silent (earlier this year.)

"They have really learnt from the initial mistakes. The ghost of the Queen still ruled the PR machine. But this is epic. It's groundbreaking, an absolute first. A tectonic shift in how the Royal Family controls its image.

"Kate's journey is profound and deeply personal, but they've learned that emotion can be controlled - and weaponised - in small, potent doses. By doing this through a polished film, they maintain dignity and control while still appearing relatable."

The video was shot by London-based filmmaker Will Warr, who has also created content for Jamie Oliver, Ed Sheeran and Stanley Tucci.
