A review is to be launched into Greensill Capital following David Cameron’s lobbying of government, Whitehall sources have confirmed to Sky News.

Mr Cameron this weekend finally commented on the Greensill Capital controversy after weeks of silence.

The ex-premier’s actions have come under scrutiny after he was revealed to have approached serving ministers and officials about the involvement of Greensill in government-backed financial support schemes during the coronavirus crisis.

This included text messages sent to Chancellor Rishi Sunak.

Mr Cameron accepted there were “important lessons to be learnt”, adding in a statement: “As a former prime minister, I accept that communications with government need to be done through only the most formal of channels, so there can be no room for misinterpretation.”

But he stressed he had broken “no codes of conduct and no government rules”.

Greensill, who employed Mr Cameron after he left 10 Downing Street in 2016, filed for insolvency earlier this month.
