The couple in Britain's most expensive divorce - at 300m - return to court over charity money
American Jamie Cooper won £337m from her former husband in a divorce battle
The couple at the centre of Britain's most expensive ever divorce are back in court after Sir Chris Hohn refused to give ex wife Jamie Cooper money from a foundation they co-founded.
The famous financier's ex-wife who won about a third of a £1 billion fortune - £337 million - in 2014.
Now Court of Appeal judges have analysed a dispute centred on the Children's Investment Fund Foundation, which Sir Chris and Ms Cooper set up when they were married, more than 15 years ago, in a bid to improve the lives of children in developing countries.
The dispute centred on whether the foundation, which has assets of more than £3 billion, could make a grant of more than £270 million to a similar charity, Big Win Philanthropy, set up by Ms Cooper after the divorce.
It involved Sir Chris and Ms Cooper and Marko Lehtimaki, another 'member' of the Children's Investment Fund Foundation.
A judge had last year ordered Dr Lehtimaki to approve the grant, following a High Court hearing in London.
But now Dr Lehtimaki asked appeal judges to review that decision by Sir Geoffrey Vos.
He argued that Sir Geoffrey had no jurisdiction to make such an order.

ShareLady Justice Gloster, Lord Justice David Richards and Lord Justice Newey, who analysed the case at a Court of Appeal hearing in London in April, have concluded that Sir Geoffrey was not entitled to make such an order and allowed Dr Lehtimaki's appeal.
Appeal judges said the litigation had its origins in the 'breakdown of the relationship' between Sir Chris and Ms Cooper.
Sir Chris Hohn, who runs The Children's Investment Fund Management, was ranked tenth on a Rich List of the world's highest earning hedge fund managers for 2015.
He was the only Briton on the list, which was dominated by Americans but also included one Norwegian – Ole Andreas Halvorsen of Viking Global Investors.
Sir Chris is one of Britain's leading hedge fund managers having set up The Children's Investment Fund Management, or TCI, in 2003.
Financier Sir Chris Hohn has refused to divert £270m to his wife for a charity she has set up
He was caught up in the row over the privatisation of Royal Mail after it emerged TCI made a huge profit buying and then selling shares for a profit – fanning the flames in the row over whether the Government had sold the company too cheaply.
Hohn's wealth is estimated at £720million even after he was told to hand over £337million in 2014 following the collapse of his marriage to Jamie Cooper-Hohn.
The couple – who had homes in London, the United States and the West Indies – had fought over assets totalling more than £700million at the High Court before a judge finally settled on the staggering sum.
The couple's long-running divorce case bordered on farce at times with Hohn accusing his ex-wife of seeking maintenance payments for a dog that never existed.
They married in Washington DC in 1995 and had four children, including triplets, before divorcing in April 2013.
