Paul McCartney has joined forces with U.K. MPs who are urging Brussels to scrap any plans to ban the use of meat-related names such as “burger” and “sausage” for plant-based products.

The proposed EU ban, if passed into law, would prohibit food producers from using designations such as “veggie burger” or “vegan sausage” for plant-based and lab-grown dishes.

“To stipulate that burgers and sausages are ‘plant-based,’ ‘vegetarian’ or ‘vegan’ should be enough for sensible people to understand what they are eating,” the former Beatles star, who became a vegetarian in 1975, told The Times of London. “This also encourages attitudes essential to our health and that of the planet.”

The proposed EU ban “could increase confusion” and “undermine economic growth, sustainability goals, and the EU’s own simplification agenda,” eight British MPs, including Jeremy Corbyn, wrote in a letter to Brussels.

The Times reported the contents of the letter Saturday evening. The missive includes the support of the McCartney family, which owns a business selling vegetarian food and recipes.

The looming ban stems from an amendment that French center-right MEP Céline Imart introduced into legislation that aims to reform EU farming rules. These proposed reforms include how farmers sign contracts with buyers alongside other technical provisions.

The bill is now subject to legislative negotiations with the Council of the EU, which represents EU governments. 

The proposed rules will become law if and when MEPs and the Council agree on a final version of the legislation to become EU law. MPs in the U.K. fear that the ban, if it survives, would also impact British supermarkets, as markets and companies across the continent are so closely intertwined.

Imart’s burger-busting tweaks were supposed to be a gesture of respect toward the French farmers that she represents — but they have divided MEPs within her own European People’s Party.

“A steak is not just a shape,” Imart told POLITICO in an interview last month. “People have eaten meat since the Neolithic. These names carry heritage. They belong to farmers.”

Limiting labels for vegetarian producers will also help shoppers understand the difference between a real burger and a plant-based patty, according to Imart, despite years of EU surveys showing consumers largely understand the difference.

U.K. MPs also cite research in their letter, stating that European shoppers “overwhelmingly understand and support current naming conventions” such as “veggie burger.”
