Burger King has become the latest fast food chain to go 'meatless' - but there's a problem for vegans.
Following the success of Quorn KFC, Greggs vegan sausage roll and more, Burger King has released the Rebel Whopper, which is made from soy.
However, perhaps surprisingly for a "plant-based" burger, it cannot be eaten by vegans or vegetarians due to the way it is cooked, Wales Online reports.
The fast food chain says the burger is aimed at "flexitarians" - in other words, people who eat meat but are cutting down on the animal-based food they eat.
Toni Vernelli, international head of communications and marketing at Veganuary, said: "For all of the important issues that Veganuary - and most vegans - are trying to address through their food choices it makes absolutely no difference whether the plant-based patty is cooked separately or on the same grill as the meat.
"What does make a big difference to animals and the planet is when non-vegans choose a plant-based menu option, enjoy it and then order it again.
"And that's exactly who Burger King's plant-based Whopper is aimed at, flexitarians who want to reduce their meat consumption for health or environmental reasons, or are considering going vegan."
Burger King marketing director Katie Evans said: "This really is a game changer - we wanted our first plant-based Whopper to replicate the indulgence and flame-grilled taste of the real thing as closely as possible, and we're thrilled with the result.
"We're delighted to satisfy the demand for this highly-anticipated product and finally bring the Rebel to the UK."
The Rebel Whopper goes on sale to anyone in the UK with the Burger King app from today (January 6) and to everyone from Wednesday (January 8).
