What family owns The Economist?

Could you please elaborate on the ownership structure of The Economist? Specifically, I'm curious to know which family holds the majority stake in this renowned publication. I've heard rumors about its family ownership, but I'm looking for a concise and accurate description of the current situation. Additionally, I'm interested in knowing if there have been any significant changes in ownership over the years, and how these changes might have impacted the publication's editorial independence and financial stability.
