Manchego cheese has become the centre of a standoff hindering a major trade deal between Mexico and the European Union.

Manchego makers in Spain argued their nation was the origin of the cheese, and want Mexico to stop using the same name, claiming it ruins the authenticity of the cheese.

Ismael Alvarez de Toledo, president of the Spanish Brotherhood of the Manchego Cheese said their cheese is made from the milk of sheep only found in the elevated region of La Mancha, unlike their Mexican counterpart.
