David Cameron has said there was "absolutely no wrongdoing" despite having a “big economic investment” in Greensill Capital, which he said did not motivate his intense lobbying of the Government for the collapsed firm as coronavirus struck.

Mr Cameron placed calls and sent dozens of texts and emails to ministers and senior officials as he appealed for their help in gaining access for Greensill to Government Covid support programmes.

Appearing virtually before the Commons Treasury Committee today, he insisted there was “absolutely no wrongdoing” in his actions and defended his lobbying efforts, but accepted that former prime ministers “need to think differently and act differently”.

Mr Cameron confirmed he was a “regular” attendee of board meetings at the financial firm headed by Lex Greensill but said there was “certainly no sense of jeopardy” over the firm’s future as the coronavirus pandemic struck.

He repeatedly refused to tell the MPs how much he stood to gain from his involvement with Greensill, saying only that he had a “big economic investment”.

“I was paid an annual amount, a generous annual amount, far more than what I earned as prime minister, and I had shares – not share options but shares in the business – which vested over the period of time of my contract,” he said.

“I had a big economic investment in the future of Greensill, so I wanted the business to succeed, I wanted it to grow.

“The fact that I have this economic interest… that’s important, but I don’t think the amount is particularly germane to answering those questions, and as far as I’m concerned it’s a private matter.”

He insisted that suggestions he was to make £60 million was a “completely absurd figure”.

“The motivation for contacting the Government was that I thought we had a really good idea for how to help extending credit to thousands of businesses,” Mr Cameron said.

Committee chairman Mel Stride told the former Conservative leader he had sent a “barrage” of texts and messages in the spring of last year when the pandemic broke.

“Many people would conclude at the time of your lobbying your opportunity to make a large amount of money was under threat,” the MP said.

Mr Cameron replied: “I have spent most of my adult life in public service. I believe in it deeply. I would never put forward something that I didn’t believe was absolutely in the interests of the public good.

“I did not believe in March or April last year when I was doing this contact there was a risk of Greensill falling over.”

Mr Cameron refused to tell the committee chairman whether his salary was higher or lower than £1 million.

“It was a generous, big salary that you might earn as someone in my position at a bank or what have you,” the former prime minister said.

As well as messaging and speaking to Mr Sunak, the former prime minister texted senior Cabinet minister Michael Gove and held a call with Health Secretary Matt Hancock.

Other recipients of Mr Cameron’s texts include Boris Johnson’s senior adviser Sheridan Westlake, Treasury ministers Jesse Norman and John Glen, and deputy Bank of England governor Sir Jon Cunliffe.

He described opposition to Greensill’s access to the Government-backed loans as “nuts” and “bonkers” in his correspondence.

Under questioning from the MPs, Mr Cameron defended approaching ministers and senior Government officials by text as opposed to email in the context of the pandemic, saying it was “a time of extraordinary crisis”.

But he added: “I think, in future, one of the lessons I take away is prime ministers should only ever use letter or email and should restrict themselves far more.”

The extent of his communications was described by Labour’s Dame Angela Eagle as “more like stalking than lobbying” as she asked if he was “at least a little bit embarrassed” about his behaviour.

Mr Cameron responded: “I was keen to get it in front of government, but as I’ve said, there are lessons to learn and lessons for me to learn and in future the single formal email or formal letter would be appropriate.”

Greensill was placed into administration in March, threatening thousands of UK jobs at Liberty Steel which was dependent on its finance.

The Financial Conduct Authority is formally investigating its collapse, having received allegations that were “potentially criminal in nature”.
