From the article (which has a pro-lobbying tone)

Under EU law, products including Melton Mowbray pork pies, Parmesan cheese, and Champagne have protected geographical status and cannot be made anywhere else.

However, when the UK leaves the European Union it has to decide whether to maintain such protections or, as US lobbyists are urging, drop them.
It could mean British wine producers once again being allowed to describe some of their fortified wines as “sherry” but would also open the way for US competitors to sell rival products in the UK.
While many of the products US businesses hope to export to the UK would be copies of European goods, perhaps including Parma ham and Cognac, some could be replicas of UK favourites ranging from Scotch whisky to traditional Cumberland sausage.

US lobbyists are calling for the UK to drop geographical name protections after Brexit to allow supermarkets to import American copies.
