Will UK power couple Christopher & Jamie Cooper-Hohn's divorce impact charity in India?

Divorce proceedings between high-profile London-based investor Christopher Hohn, founder of the Children's Investment Fund Management UK LLP, and his wife Jamie Cooper-Hohn have turned contentious.

A London court has ruled out a possibility of Cooper-Hohn submitting evidence to support her claim that she is owed half of her husband's business. Hohn's lawyer had claimed she is entitled to about a quarter of his stake in the hedge-fund management companies of TCI, which he valued at about $100 million and are wholly owned by him.

Cooper-Hohn, 49, is demanding half. Hohn, 47, is well-known for his activist investing, buying large stakes in companies and pressuring management to make changes that might drive up the share price. His hedge fund, known as TCI, owns stakes in Moody's Corp and Royal Mail Plc.

The fund has about $8 billion in assets under management, his wife's lawyer, Martin Pointer, said in court documents. He and his wife also set up the charity Children's Investment Fund Foundation (CIFF ), which works across Africa and India. Cooper-Hohn is the chairman of CIFF.

Hohn has generated wealth of about $ 5.7 billion in his working life, including $4.3 billion for charity and $1.36 billion now owned by the couple.
