Last year, the then-Prince of Wales revealed his future plans for Sandringham, telling Country Life that he plans to turn it into a "fully organic operation".
Charles took over running the Norfolk property, where their family have traditionally celebrated Christmas, from his late father Prince Philip in 2017, and is now focused on running it in a way that works with rather than against the environment.

He told the magazine, "Since the beginning of the 1980s, when I first had responsibility for managing some land in my own right at Highgrove, I have wanted to focus on an approach to food production that avoids the impact of the predominant, conventional system of industrialized agriculture, which, it is increasingly clear to see, is having a disastrous effect on soil fertility, biodiversity and animal and human health."
He went on to explain, "It has always seemed to me somewhat logical to embrace a farming system that works with Nature and not against her, thus restoring the lost fertility and carbon-sequestration capacity of the soil on which we rely for our very existence upon this planet."
