However he allegedly failed to warn customers and pub manager Paul Wilson, 38, who suffered a severe peanut allergy, died at his home after eating a curry made with the cheaper ingredient.

The waiter who took his order and the chef who prepared the meal were both in breach of immigration laws and working illegally.

Less than a month earlier, on January 3rd 2014, student Ruby Scott, 17, who suffered the same allergy, had already fallen seriously ill after suffering anaphylaxis - a severe allergic reaction - having eaten a chicken korma from another of Zaman's restaurants. She was saved after being rushed to hospital and injected with an epi-pen.

Her mother later rang the restaurant, The Jaipur in Easingwold, North Yorks, to ask whether it contained peanuts but she was assured it did not and had been safe for allergy sufferers.
