Warren Buffett gives away more of his fortune

Warren Buffett, the world's third richest man, has announced a donation of $1.9bn (£1.25bn) worth of shares to charitable foundations.

Among the beneficiaries are the Bill and Melinda Gates Foundation, and charitable foundations run by Mr Buffett's children. Mr Buffett, 79, made his fortune as an investor, and has pledged to give away 99 per cent of his wealth. This year's giveaway was larger that the previous one due to rising share values.
