Stricter food labelling laws prompted by the death of a teenager who ate a Pret A Manger sandwich could be in place as early as next summer, her parents said.

The parents of Natasha Ednan-Laperouse met with Environment Secretary Michael Gove, who told them he wanted "Natasha's Law" to be introduced next year.

The 15-year-old, from Fulham, west London, collapsed on board a flight to Nice in 2016 after eating a sandwich she bought at Heathrow Airport containing sesame seeds, to which she was allergic. She died later in hospital.

Natasha's father, Nadim, said: "I think we are moving to a tipping point, a really crucial point... a fundamental point for things to actually change in society, for people to become conscious in their conversations and their thoughts about allergies.

"So things that have previously been in the dark, are now going to come out into the light.

"And that's really really important, and only good will come from that."

He said of the meeting with Mr Gove: "It was so positive actually we were taken by surprise, and that's a wonderful thing for us, in our situation and also for all the other people who have allergies in this country."
