A hedge fund boss who employed Kwasi Kwarteng as a political consultant more than a decade ago has seen his firm make millions by betting against the tumbling pound.
Tory donor Crispin Odey - who The Mirror previously revealed made £220 million overnight after the Brexit vote - has overseen a 145% rise in his company's main fund this year, sources said.
Mr Odey, who has donated more than £75,000 to the Tories since 2017, and also ploughed £10,000 into former PM Boris Johnson's leadership campaign, said his policy of betting against the pound had been "helpful".
