My brother Imran Imam’s passion was mathematics and science. He gained a master’s in mathematical physics at Imperial College London in 1978, and got a job offer from the aircraft manufacturer Hawker Siddeley, but because he did not want to work on missiles he decided to go into banking instead.
Imran, who has died aged 70, began his working life at the Bank of Credit and Commerce International in London. However, he became a “whistleblower” about corruption in the banking system and was one of those who gave evidence at the subsequent inquiries into BCCI’s activities. An international investigation found that the bank had broken lending laws and operated an extensive money-laundering operation. Imran’s help was crucial in recovering several hundred million pounds of investors’ funds.
