Melinda French Gates, the former wife of Microsoft co-founder Bill Gates, announced on Monday she would resign as co-chair of the Bill & Melinda Gates Foundation next month.

French Gates said in a statement on X that it was a “critical moment” to protect and advance women’s rights around the world.

She said will have “an additional $12.5 billion to commit to my work on behalf of women and families” as a result of her resignation and the Gates’ prior divorce agreement. The couple divorced in May 2021.

Bill Gates in a separate statement said, “I am sorry to see Melinda leave, but I am sure she will have a huge impact in her future philanthropic work.”
