Just Eat UK managing director Andrew Kenny said: “We’re proud to be the only food delivery app that can bring you the likes of the Greggs vegan sausage roll wherever you are.

“This is an exciting exclusive partnership for Just Eat. Greggs has proved extremely popular with our customers, especially during breakfast, demonstrating that as a nation we love the convenience of getting our favourite food delivered.”
