Amateur night moved swiftly away from the spin doctors into the notebook of one reporter who wrote (sic): “The Finance Secretary blasted Jim McColl, a former economic adviser to the SNP government, saying if it weren’t for the Scottish Government then the yard on the Clyde would have went into administration.”

McColl then suggested that Sturgeon misled parliament last week when she claimed the contracts were signed off by disgraced former minister Derek Mackay — and she had.

Whether she did it knowingly or unknowingly is a matter for the First Minister, but Mackay had come up with the excuse of every politician in trouble: “It wisnae me!”

And then he added that he was on holiday at the time the dastardly deed was done.

Now the Opposition parties at Holyrood want an inquiry to establish why the government dropped a requirement for full repayment guarantees if the billionaire McColl’s Ferguson Marine yard failed to build the ships on time or went bust.

McColl told The Sunday Times that said SNP Ministers acted in haste and against the advice of ferry company CMAL so the contract could be announced with a fanfare at the party’s  autumn conference in 2015. It was.

He said the contracts were awarded “for political purposes” and “everything was about the optics and timing of the announcements for political gain.”

The row, like an old Calmac ferry heading out for Mull in a Force 9, rumbled on to the radio.

Forbes told Good Morning Scotland that the delays, which could be up to five years or more,  were down to the construction of the vessels.

She added: “The Audit Scotland report said there were no material issues with the procurement process, and in terms of the full refund guarantee mitigations were put in place.

“On that balance of risks, if we pulled the plug on the contract at that point we wouldn’t have proceeded with those two vessels.

“The yard, of course, would probably have gone into administration.

“The root cause of the delays is the construction, it’s not the contractual arrangements. The full refund guarantee is an important issue.”

Reporter Gary Robertson asked: “The other issue is it not that this was actually given the go ahead, that actually the designs hadn’t been fully worked out?”

Forbes replied: “Well, you highlight another important point which comes back to construction.  We are focused here on procurement and refund guarantees. The fundamental problem here was the construction process.

“We had a private company that won a contract fairly and squarely and the construction process was inefficient and Audit Scotland unpacks this further.”

Robertson asked: “Was the problem here the rush to announce some good news at your party conference?”

Forbes replied: “I fundamentally disagree with that.  Again, I would say if we’re serious about learning the lessons of this whole situation, we’ll base that analysis on facts in the independent Audit Scotland report and not the opinions of somebody with a vested interest in a Sunday newspaper.

“That timetable does not stack up. Ferguson ‘s was publicly announced as the preferred bidder in August 2015.

“I think the conference you’re referring to was sometime in October. The election wasn’t until the following May and this whole process was months if not years in the making.”

Does Katie think we all came up the Clyde in a banana boat?  That she really can’t remember when that SNP conference took place?

One person who certainly did is LibDem Willie Rennie, who told The Democrat: “Instead of trashing the reputation of Jim McColl, the Scottish Government should now just confess that they gambled hundreds of millions of pounds of taxpayers’ money to get them a cheap headline. 

“We have heard the repeated denials from Kate Forbes who wasn’t a minister at the time, now we need to hear from SNP politicians who were responsible for this cynical misuse of public funds. John Swinney, Keith Brown and Nicola Sturgeon must give evidence to a public inquiry under oath.     Islanders who are angry they don’t have a reliable ferry service deserve answers.”
