The coronation of King Charles the Third is upon us.

But away from the street parties and the pomp at Westminster Abbey and Buckingham Palace, we are going to focus on the new King’s impact on agriculture.

As Prince of Wales, Charles was a long-time advocate for sustainable agriculture – sometimes getting in trouble for expressing his views.

Once described as a one-man NGO, he was arguably ahead of his time as a high-profile figure talking about things like climate change, pollution, and organic produce.

But why was he so focused on the environment? Just how influential has he been? And how will things change now that he is king?
