The National Farmers’ Union (NFU) says it has seen an unprecedented demand for its banner promoting British produce.

It is printing more after than 300 farmers signed up for one in just one month.

NFU President Meurig Raymond said they had improved the visibility of members’ farms.

“The food flag design we created on the ‘Proud to Produce’ banner is an out-and-out celebration of all of the wholesome food that British farmers and growers produce each and every day,” he said.

“We are so proud that members from across the country are displaying their banners on their farms. Located on prime sites, farmers are using the banners to grab consumers attention with thousands of people a day seeing our #BackBritishFarming message.”

The NFU said it had seen a rise of almost 20% in the number of farmers ordering the banner this year.
