McDonald’s has launched a limited edition “Irish” burger, called the McMór. A Sinn Fein MLA has branded it “partitionist” because it will only be available in the Republic of Ireland.

The fast food chain has called the burger, which will only be available for six weeks, a "tribute to the best produce and the finest flavors from across Ireland.”

The McMór, which McDonald’s is marketing as Gaelic for Big Mac, is made with 100% Irish beef, a “potato-flaked" bun, bacon, shredded cabbage, kale, and Ballymaloe Relish and Charleville Cheddar, the Belfast Telegraph reports.

West Tyrone MLA Barry McElduff told the Irish News: "It is not 'mór go leor' (big enough) because it does not incorporate the six counties. If it's available in Letterkenny then it should be available in Omagh," he said.

"There is a popular McDonald's in Omagh and I know the patrons in the county of Tyrone would fully expect to have the choice of a McMór.

"McDonald's is a global firm and some people have concerns about its ethics, but we can now add the sin of partitionism to the list."

A McDonald's spokesman responded, saying: "The McMór was developed by the McDonald's business in the Republic of Ireland for customers in this market specifically.

"McDonald's Northern Ireland is part of the McDonald's UK business."

The sandwich was created by the McDonald’s Ireland Chefs Council, which held its first meeting last year aiming to create a burger with real Irish flavors.
