Carlo Petrini, founder of Slow Food, dies aged 76

Slow Food pioneer Carlo Petrini, who spent four decades promoting sustainable food production and traditional cooking, has died aged 76 in his Italian hometown.

He founded the movement with a small group of friends in the countryside following protests against the opening of Italy's first McDonald's in 1986.

It quickly spread through the country and eventually expanded into more than 160 others, with Petrini as its president. He became friends with King Charles III and the late Pope Francis through his campaigning.

Announcing his death, the organisation said Petrini had been a visionary who "brought to life a global movement rooted in the values of good, clean, and fair food for all".

His work connected "communities, farmers, food artisans, cooks, activists, and young people across the world", it added.

Italian President Sergio Mattarella said his death left a "huge void not only in the world of food and wine science, but also in society as a whole, and not just in Italy".

Petrini, who was a journalist, set up the grassroots movement under the name Arcigola shortly after demonstrations against McDonald's opening a restaurant in Rome's Piazza di Spagna.

By 1989, the Slow Food Manifesto was signed by over 20 global delegates - pledging to "escape the tediousness of fast-food" by "defending old-fashioned food traditions".

His work saw him become friends with King Charles, as the pair bonded over their shared beliefs in fresh and sustainable food.

And in 2013, Petrini said he was "surprised" when Pope Francis telephoned him after he had sent him a book and a letter.

He told Italian newspaper La Repubblica: "Our phone conversation ended, with wishes of good health and a mutual embrace.
