MCDONALD’S says it has divided burger fans by changing the Big Mac for the first time since its creation in 1968.

The fast food giant has added bacon to the popular menu offering and has also brought back the Grand Big Mac and Mac Jr.

Bosses say some customers are questioning if the burger should even be classed as a Big Mac at all, while others are welcoming the new addition into the Big Mac family.

The chain is inviting the public to join the debate by using the hashtags #NotABigMac or #StillABigMac.

Michelle Graham-Clare,head of marketing at McDonald’s UK and Ireland, said: “The customer reaction to our Grand Big Mac and Mac Jr. last year was phenomenal - the love for the iconic Big Mac surpassed all expectations.

“This is why I’m delighted to introduce bacon to the Big Mac range, a twist on a classic which has sparked debates around the world: is a Big Mac still a Big Mac if you add bacon?”

The range is available until March 19.
