MPs are wearing corn ears (wheatsheaves) today to show support for "Back British Farming Day," an annual event organized by the National Farmers' Union (NFU). This day celebrates British farming and the importance of the agriculture sector to the UK economy and communities. The wheat sheaf pin badges worn by MPs symbolize their support for British farmers, highlighting the significance of British food production and farming standards. The event encourages politicians and the public to prioritize and recognize the contributions of farmers and growers. This tradition has been ongoing for several years and is usually observed around early to mid-September during parliamentary sessions.
