The biggest donation of last year came from, perhaps unsurprisingly, the richest person in the world – Bill Gates, who has a net worth of $86bn, according to Forbes.

The Microsoft founder and his wife Melinda gave company stock valued at around $4.6bn to their private Gates Foundation, which aims to enhance healthcare and reduce poverty around the world, as well as improve the US education system.

Facebook co-founder and fifth richest man in the world Mark Zuckerberg, and his wife Priscilla Chan, were the second most generous philanthropists last year. They gave their Chan Zuckerberg Foundation, a nonprofit arm of their Chan Zuckerberg Initiative, just under £2bn. The company's aim is to "advance human potential and promote equality in areas such as health, education, scientific research and energy".
