"George Soros did not speculate against sterling while he was arguing for Britain to remain in the European Union," a spokesman for Soros said on Monday. "In fact, he was long the British Pound leading up to the vote."

"However, because of his generally bearish outlook on world markets, Mr. Soros did profit from other investments," the spokesman said.
