They are wearing ears of corn (wheat sheaves) in Parliament to show their support for British farming. This is part of an annual event called "Back British Farming Day," organized by the National Farmers' Union (NFU). MPs wear these badges made from British wheat and wool as a symbol to remind politicians of the importance of British food and farming standards, to celebrate the farming industry, and to advocate for policies that support British farmers and maintain high standards for food production. The campaign highlights the significant contribution of farming to the UK economy and employment, and it encourages MPs to pledge support for British farming in trade and policy discussions. The symbol of the ear of corn (or wheat sheaf) represents the agricultural heritage and ongoing support for the farming community in the UK.
