Reports emerged that Cameron had lobbied Chancellor of the Exchequer Rishi Sunak in 2020 to change rules in order to allow Greensill to join the Covid Corporate Financing Facility, a government loan scheme that was initiated to support companies during the pandemic-related economic recession.
A Cabinet Office inquiry found Lord Heywood to be primarily responsible for Lex Greensill's being given a role in government and access into 10 Downing Street.
[2] During Cameron's 2010–2016 premiership, financier Lex Greensill, suggested by the image of a business card published by the Labour Party to be a senior advisor to the Prime Minister,[3] was alleged by The Sunday Times to have had access to eleven departments and agencies.
[19] On 12 April 2021 the government announced a Cabinet Office inquiry into the lobbying activity performed on behalf of Greensill, to be led by specialist finance solicitor Nigel Boardman, a non-executive board member of the Department for Business, Energy and Industrial Strategy.
[21][10] It also concluded that Cameron "did not breach the current lobbying rules and his actions were not unlawful" and that he "on occasion understated the nature of his relationship with Greensill Capital".
[25] The report also said that the current rules had "insufficient strength", and that there was a "good case for strengthening them" and that in his lobbying of Greensill, Cameron had shown a "significant lack of judgement".
[25] On 28 June 2021, the Financial Reporting Council announced that it had opened an investigation[26] into the audit of Greensill Capital (UK) Limited by Saffery Champness LLP.
The SFO had questioned witnesses about Cameron’s involvement with Greensill as part of a wider inquiry into "suspected fraud, fraudulent trading and money laundering" in GFG Alliance companies.
