The Giving Pledge

Billionaire MacKenzie Scott, ex-wife of Amazon founder Jeff Bezos, has donated another .7bn  to a range of charities.

Ms Scott said in a blog post that she wanted to give the money to those "that have been historically underfunded and overlooked".

She wrote that she had chosen 286 organisations working on racial inequality, the arts and education.

MacKenzie Scott, philanthropist, author and former wife of Amazon founder Jeff Bezos, has married a Seattle science teacher who expressed gratitude "for the exceptional privilege it will be to partner in giving away assets with the potential to do so much good when shared."
