The popular McDonald's Grand Mac burger is returning to the UK - but for a limited time online.

Glasgow Big Mac fans will be able to get their hands on the creation, which has already been out in the UK twice, from Wednesday, January 29.

Just like when it was rolled out last year, fast-food fans will be able to add bacon to the burger, which comes even bigger than the Big Mac.

Thomas O’Neill, Head of Food Marketing at McDonald’s UK&I, said: “As our most iconic McDonald’s product, we are excited to be bringing back this twist on our classic Big Mac, so fans can spend longer with the taste they love this Winter.

"It’s a firm favourite among our customers and we are delighted to bring it back once more for a limited time. 

"The reaction to the news of our forthcoming limited run of Big Mac Special Sauce dipping pots has been fantastic.

"We are working hard to produce as much as we can before the launch in a few weeks in order to give as many people as possible the chance to enjoy Big Mac Special Sauce with all of their favourite menu items."

The Grand Big Mac will run for eight weeks only.

And, from February 12, fans will be able to order 50ml pots of extra Big Mac Special Sauce.

The sauce will be on sale for 50p.
