Peter Murrell, the husband of the former Scottish first minister Nicola Sturgeon, has been rearrested and questioned for a second time by police investigating allegations of financial wrongdoing by the Scottish National party.
Murrell, the former chief executive of the SNP, was first arrested and interviewed as a suspect by Police Scotland detectives in April 2023 at the home he shared with Sturgeon in Glasgow, but was released later that day pending further investigation.
The police erected tents at the front of their detached house, searching the garden and removing evidence from the property.
In a series of linked operations, detectives also searched the party’s headquarters in Edinburgh and confiscated a luxury motorhome parked in the driveway of Murrell’s 92-year-old mother in Dunfermline.
They later arrested the party’s then treasurer and SNP MSP Colin Beattie at his home in Midlothian, interviewing him under caution before releasing him without charge on the same day.
Two months later, on 11 June, Sturgeon was arrested and interviewed by arrangement with police, before also being released without charge.
She has repeatedly denied any wrongdoing and says the police investigation into the SNP, known as Operation Branchform, had nothing to do with her decision to quit as Scotland’s longest-serving first minister in March 2023.
With speculation mounting about the status of the investigation, Police Scotland announced on Thursday afternoon that Murrell had been taken back into custody at 9.13am that morning. The 59-year-old had been rearrested “in connection with the ongoing investigation into the funding and finances of the Scottish National Party”, the force said.
“The matter remains active for the purposes of the Contempt of Court Act 1981 and the public are therefore advised to exercise caution if discussing it on social media.
“For this reason, Police Scotland has turned off the comments function on this post. As the investigation is ongoing we are unable to comment further at this time.”
An SNP spokesperson said: “It would be inappropriate to comment at this stage.”
Operation Branchform was launched by Police Scotland in July 2021 after a series of complaints about the SNP’s finances, which focused on the status of £667,000 in donations for a pro-independence fighting fund.
The party’s accounts did not clearly show where that money was held, sparking allegations it had been used for the SNP’s day-to-day spending. The party said the money had been “earmarked” through its internal accounting processes.
The party was rocked by a series of disputes about the transparency of financial decision-making, with three members of its finance and audit committee resigning in March 2021 after complaining they were not allowed to see the party’s accounts.
Two months later the MP Douglas Chapman resigned as its then treasurer, followed by the resignation of fellow MP Joanna Cherry from her position on the national executive committee.
With the party’s finances stretched, in June 2021 Murrell had loaned the party £107,000 “to assist with cashflow” with half of it repaid to him by October 2021. News of the loan did not emerge until December 2022.
Jackie Baillie, the deputy leader of Scottish Labour, said: “This is another incredibly concerning development in this long-running investigation. It is essential that Police Scotland is able to proceed with this investigation without interference.”
