The Aga Khan Development Network was founded by the Aga Khan, the name given to the hereditary Imam of the Shia Ismaili Muslims, and operates mostly in Africa, Asia and the Middle East.
Its mission is to help the poorest parts of those areas and usually concentrates on the fields of health, education and rural development.
It has a huge annual not-for-profit budget for these of £735million a year and has 80,000 staff on its books.
The AKDN says it gets most of its funding from partnerships with national governments and private sector partners.

These team-ups include some 19 UK based names, including Boris Johnson’s government.
The Aga Khan himself (pictured above with his ex-wife) also contributes a vast amount from an estimated £800million wealth, which comes from tithes from Ismaili community members.
He gets income from a multi-million-pound horse-racing and breeding operation in France and Ireland and has been referred to as a ‘playboy’ in the past.
In 2014 he divorced his second wife after a ten year legal battle – paying her £50million.
His personal wealth also allowed him to run a £100m yacht, named Alamshar after one of his racehorses and at one point he owned famous missing horse Shergar.
In a rare interview in 2017 he said: ‘Climate change is a major threat to much of the developing world, and it needs to be looked at with great care’.
