Police Scotland Assistant Chief Constable Stuart Houston led the force’s four-year investigation into Murrell, codenamed Operation Branchform.

He says the jail sentence is proof that those who “embezzle vast sums of money will not escape justice, regardless of how high a profile or role they may hold”.

ACC Houston says Murrell’s “calculated” crime “proved his disregard for those who placed their trust in him”.

Sean Clerkin - the first person to report concerns about the SNP's funds - claims he was turned away from the first police station where he attempted to file a complaint.

He then attended a second in Barrhead, Renfrewshire, in March 2021 where officers took a statement.

Within five hours he says police were at his door, leading him to believe they were already looking into the SNP’s finances.

Asked if he feels any personal satisfaction, Clerkin says: “Some satisfaction but not complete satisfaction.

“We need to get to the bottom of it. There is a lot more to come out.”

The court previously published 125 pages of documents detailing Murrell's purchases.

BBC Scotland’s data visualisation team has published a searchable database of the items he bought with SNP money from 2010 to 2022.

The largest single transaction, in 2020, was £124,550 for a luxury motorhome paid for entirely with party funds.

Murrell was accused of creating false documents to disguise the payment as a legitimate party expense.

His first major purchase, a £33,000 Volkswagen Golf, was made in early 2016 using £16,489 of SNP money.

He used £57,500 of party cash to buy a Jaguar I-PACE car in 2019, and sold it for £47,378.76 two years later.

Murrell also used SNP funds to purchase two Bremont watches for a total of £9,350, a £4,225 Starwalker World Time fountain pen and a £3,500 Hamilton and Inches silver wine coaster.

Russell Findlay has accused John Swinney and Nicola Sturgeon of “enabling” Peter Murrell’s embezzlement from the SNP.

The Scottish Conservative leader said those who raised concerns about the party’s finances had been “warned” about doing so, allowing Murrell’s theft to continue.

He said Murrell got away with a “brazen and large-scale crime spree”.

Findlay added: “It’s no wonder that Swinney is so desperate to thwart an inquiry which would examine many issues, including whether public money was stolen.”

Clerkin says he is looking at three further legal options.

The first is a private prosecution, in England or Scotland, against Nicola Sturgeon - who was told by police last March that she was no longer under investigation.

The second is a class action on behalf of those who donated money to the party.

And the third is to demand a Crown Office review into the decision not to prosecute Sturgeon.

The campaigner also calls on first minister John Swinney to issue a public apology and to offer to compensate those who lost money as a result of the scandal.

Outside court after the sentencing, Clerkin spoke to the media.

Asked if he felt sorry for Murrell, Clerkin says: “I don’t have any sympathy for him whatsoever.

“There are people who have donated money and have since died and their families are left feeling angry.”

The political activist also calls the case into what happened to the SNP’s £667,000 fund for a second independence referendum to be reopened.

He tells the media that former first minister Nicola Sturgeon - who was arrested under Operation Branchform and later released without charge - has questions to answer.

Police Scotland first received a complaint about possible mismanagement of SNP finances in March 2021.

Concerns around the party's independence referendum campaign fund had been raised in online blogs.

But the first person to report the matter was political activist Sean Clerkin.

Officers then received around 12 further reports, mainly from donors via email or online contact forms.

Operation Branchform was set up and officers work closely with specialist economic crime detectives, based at the Scottish Crime Campus at Gartcosh, to piece together a complex jigsaw.

Murrell's punishment won't end with his releasepublished at 10:30 BST

As a long-term prisoner, Peter Murrell will be eligible for parole halfway through his sentence - that will be after he has served about two-and-a-half years.

Assuming he is of good behaviour, we can expect the parole board to sanction his release at that stage.

It’s also very likely that he could be freed earlier than that under a home detention curfew, with a tag and controls over his movements.

As his lawyer noted this morning, his punishment won’t end there. Peter Murrell’s reputation is in ruins.

One last point - his defence team will be considering whether Lord Young has gone too far. They may well appeal in an attempt to have that jail term reduced.

The next major development in this case will be a proceeds of crime hearing which has been scheduled for 14 September in Edinburgh.

The amount Murrell must pay back has not been made public and will be based on a series of calculations, which will include inflation.

One thing we do know is that he intends to fully repay what is often described as his ill-gotten gains.

During the hearing Lord Young sought clarification that the funds in question were under Murrell’s sole control.

His lawyer, John Scullion KC, confirmed that was the case.

Scotland’s new Lord Advocate has hailed the work of police and prosecutors following Murrell’s sentencing.

Ruth Charteris KC, who was only appointed to the position of the country’s top law officer last week, said more than 500 witness statements were taken during the investigation.

She said it had been a “lengthy and high-profile case conducted under significant scrutiny”.

John Logue, chief executive of the Crown Office and Procurator Fiscal Service (COPFS), said it was “understandable” that the public wanted more information on the case given the high level of public interest.

But he said the investigation had to be allowed to take its course.

“It would not have been appropriate to comment in detail while the criminal investigation and court proceedings were ongoing,” he said.

“As in all cases, prosecutors had to protect the investigation and act fairly to everyone involved.

“Criminal cases require careful, evidence-led preparation and decisions reached through normal legal processes.”

Huge moment in the history of devolutionpublished at 10:16 BST

This is a hugely significant moment in the history of devolution.

Peter Murrell was a towering figure in the SNP and central to its transformation from a fringe organisation to an election-winning machine.

But from 2010 to 2022, a period when he masterminded victories in three Holyrood and three UK elections - in terms of seats won in Scotland - he was embezzling money from his own party.

It is a truly remarkable case that will be talked about for years to come.

Peter Murrell's defence KC, John Scullion, told the judge that the former SNP chief executive accepted full responsibility for his actions and had expressed remorse and guilt.

An unimaginable fall from power for Murrellpublished at 10:12 BST

Ten years ago today Peter Murrell was contemplating the result of the UK’s referendum on its membership of the European Union.

As chief executive of the SNP his focus would have been on what the outcome of the Brexit vote would mean for his party and, more widely, the Scottish independence movement.

It would have seemed unimaginable then that, a decade on, he would be leaving the High Court in Edinburgh to start a prison sentence of five years and three months.

To be honest, despite having just witnessed his departure from the dock, it still seems unimaginable now.

I was sitting with the pool cameras allowed in the main body of the court to film the sentencing hearing.

I could see Peter Murrell handcuffed by his right hand to a prison officer as he arrived in court, wearing a dark suit and navy tie.

The metal cuffs could be heard jangling as he walked to the dock. They were unlocked before he sat down.

When the hearing began he looked straight ahead, blinking, as his defence lawyer told the court that Murrell expected no sympathy.

As well as the cameras in court there was also a sketch artist, another rarity in Scottish courts.

She was studying Murrell as he sat in the dock and took some notes before leaving the court room to start her sketch.

As he was sentenced, Murrell looked straight ahead listening to the judge. He showed no emotion as he was told he would serve five years and three months in jail.

He was then again cuffed by his right hand and led out of court to prison.

We hoped for some clarity on Murrell's motives today, but many questions remain unanswered.

Indeed Lord Young told the former SNP chief executive that it is “very difficult to get a clear picture for what drove your actions”.

During his three public court appearances, Murrell has cut a lonely figure.

Not once did he glance in the direction of the packed public gallery.

There may well have been a friendly face to offer support in his darkest hour but, if so, the former SNP chief executive did not lock eyes with them.

The court today heard he faces a bleak and solitary future as a result of his crimes.

Murrell has been sentenced to five years and three months imprisonment.

The sentence has been reduced from seven years, which would have been imposed if he had been found guilty after a trial.

The judge says he reduced the sentence because Murrell pleaded guilty at the preliminary hearing.

The sentence has been backdated to 25 May, which is when he was first remanded in custody.
