Hedge fund
Rank 2017

London-based Hintze, 63, said Britain had more to fear from staying in the EU than leaving and gave £100,000 to one of the main Brexit campaigns. Born in China to Russian parents, he served three years in the Australian army before coming to the UK in the 1980s and working in the City for Goldman Sachs. He is the majority owner of the CQS hedge fund, which has £9.5bn under management. He established the Hintze Family Charitable Foundation, backing projects ranging from theatres and hospitals to churches and schools. He has spent at least £77m on Australian property and farmland.
