Jack Hinchliffe, Innovation Director at KFC UK & Ireland, said: “There’s been so much excitement for the Double Down since it first launched to the US in 2010. It’s sold out in every country that it’s been released in.
“Fandom has gone wild over the past few years on social media, and we’ve even had reports of our customers taking things into their own hands by hacking the menu to create the sandwich."
The Double Down will be priced from £4.79 – or from £5.79 with fries and a drink.
