BORIS Johnson was cut off by the Commons Speaker for failing to answer a question about an inquiry into the Greenshill scandal.

Ministers and the Civil Service have been dragged into the row over Greensill Capital’s links with government and former prime minister David Cameron’s lobbying for the financial firm.

Labour’s calls for a parliamentary inquiry intensified after it emerged that the former head of Whitehall procurement became an adviser to Greensill Capital while still working as a civil servant, in a move approved by the Cabinet Office.

Correspondence between the Cabinet Office and the head of the official Advisory Committee on Business Appointments (Acoba) has revealed that Bill Crothers joined Greensill as a part-time adviser to the board in 2015.

Crothers was still working as a civil servant when he took up the advisory role, a move which he said was approved by a conflicts of interest policy and “supported by the Cabinet Office leadership”.

He left the civil service later that year, after three years as the Government’s chief commercial officer, and subsequently became a director at Greensill.

Labour leader Keir Starmer accused Boris Johnson of “blocking a proper inquiry”, adding: “The Greensill scandal is just the tip of the iceberg. Dodgy contracts, privileged access, jobs for their mates, this is the return of Tory sleaze.

"It’s now so ingrained in this Conservative Government, we don’t need another Conservative Party appointee marking their own homework.

“The more I listen to the Prime Minister, the more I think Ted Hastings and AC-12 is needed to get to the bottom of this one.

“We know the Prime Minister will not act against sleaze, but this House can.”

He pressed MPs to back Labour’s motion in a bid to start to “clean up the sleaze and cronyism that’s at the heart of this Conservative Government”.

Johnson highlighted the independent review, insisting there are “tougher” laws on lobbying before adding: “We’re getting on with rooting out bent coppers. We’re also appointing and hiring thousands more police officers and fighting crime on the streets of our cities while they oppose the police and crime Bill.”

The Prime Minister continued attacking Labour’s opposition to the legislation, with Speaker Sir Lindsay Hoyle cutting him off and telling the Commons: “Prime Minister, I think we ought to at least try and address the question.”

Johnson earlier said he shares the “widespread concern about some of the stuff that we’re reading at the moment”, and Cabinet Secretary Simon Case also has concerns.

“I do think it is a good idea in principle that top civil servants should be able to engage with business and should have experience of the private sector,” the PM said.

“When I look at the accounts I’m reading to date, it’s not clear that those boundaries had been properly understood and I’ve asked for a proper independent review of the arrangements that we have to be conducted by Nigel Boardman, and he will be reporting in June.”

In a letter to civil service chief operating officer Alex Chisholm following the reports, Acoba chairman Lord Pickles questioned why the committee had not received an application from Crothers in relation to his role at Greensill.

In correspondence which was published yesterday, Chisholm said Crothers had taken a role advising the board of Greensill in September 2015 while employed as a civil servant.

In a letter to Lord Pickles, Crothers claimed he did “completely respect the required process” and had been told no application was required to be submitted to the committee.

“It was seen as a way of me transitioning back into the private sector and was supported by the Cabinet Office leadership,” Crothers said in the letter.

“This advisory role was not seen as contentious, and I believe not uncommon. I then left the civil service in good stead and with best wishes.”

In response, Lord Pickles criticised the “lack of transparency” around Crothers’ part-time employment with Greensill, and urged the Cabinet Office to publish the conflicts of interest policy."
