The head chef of Noma, one of the highest-rated restaurants in the world, has resigned amid allegations of abuse.

René Redzepi announced his exit on social media, saying: "After more than two decades of building and leading this restaurant, I've decided to step away and allow our extraordinary leaders to now guide the restaurant into its next chapter."

Former employees had accused the chef of creating a toxic work environment, including verbal and physical abuse, according to media reports.

The fine-dining establishment, which is based in Denmark, has been preparing for a Los Angeles residency, but corporate sponsors pulled out after the abuse claims and protests outside his pop-up location.

In a statement posted on Instagram, Redzepi said: "An apology is not enough; I take responsibility for my own actions.
