Bill Gates Vows To Drop Off World Rich List

Billionaire Bill Gates has pledged again to give his wealth away, adding that he will eventually drop off the world's rich list.
It came as the Microsoft co-founder announced he would make a $20bn (£17bn) donation to his philanthropic fund.
The world's fourth richest man said he had an obligation to return his resources to society.
Mr Gates first pledged to give away his wealth in 2010 but his net worth has more than doubled since then.
He is currently worth $118bn, according to Forbes magazine, but that will fall significantly after his donation in July to the Bill & Melinda Gates Foundation, the charitable fund he set up with his ex-wife in 2000.

The Gates Foundation works in countries to eradicate diseases such as Malaria, improve education and tackle poor sanitation. It was thought to be the world's second largest charitable foundation in 2020, holding $49.8bn in assets and is backed by other wealthy benefactors such as the billionaire investor Warren Buffett.
Although the foundation has done good work, some have raised concerns about the ethics of a private endeavour wielding such great influence.
The foundation is the largest private donor to the World Health Organization, second only to the US with its annual donation in 2018. Concerns about this became more pointed after former President Donald Trump threatened to pull US funding.
Mr Gates held Forbes' title of the richest person in the world between 1995 and 2010, and again from 2013 to 2017.
Amazon founder Jeff Bezos knocked him off the top spot in 2017 before Tesla chief executive Elon Musk took pole position in 2022.
