He escaped Nazi-occupied Paris, flew for RAF - and is on the Rich List aged 100

Murray, whose father perished at Auschwitz, returned to Paris to take control of the family's construction company after the war. He went on to build up a fortune worth an estimated £2.3bn.

In the UK his family’s business interests include London Security, which makes extinguishers and other fire-protection equipment, and Andrew Sykes Group, an air-conditioning, heating and pumping kit hire company.

The businessman, who celebrated his 100th birthday in February, is not thinking of hanging up his hat just yet. “What am I going to do if I retire? Creating businesses is what I do,” he said. 

He is the oldest person to join the Rich List since 2014, following the death of industrialist Sir Bernard Schreier at the age of 95.
