Former Prime Minister David Cameron has said that he first became concerned that Greensill Capital might be in "serious financial difficulty” in December 2020 following a call he had from the founder of the now-collapsed supply chain finance firm.

Evidence released ahead of a hearing of MPs later today shows Cameron described the firm's controversial leader Lex Greensill as a "friend" as he corresponded with leading government figures ranging from Rishi Sunak to Michael Gove in a bid to curry favours for the business.
