FOR almost a decade Peter Murrell and Nicola Sturgeon were the husband and wife team in charge of the SNP.

But in 2023 Ms Sturgeon, who became both SNP leader and Scottish First Minister in 2014,  quit those roles, while the contest to replace her divided the party and saw her husband dramatically resign.

Mr Murrell, 58, who had been party chief executive since 1999, was the man responsible for the day-to-day running of the SNP, which was at one point the second largest party in the UK.

That job meant Mr Murrell was one of the most influential figures in Scottish politics, despite having never been an elected politician or a figure much in front of the cameras.

However, he announced he was resigning with immediate effect on March 18 2023 amid a row over the party's membership numbers and transparency.

It comes almost a quarter of a century after he succeeded Michael Russell, the current SNP president, as the party's chief executive, who is now taking on his work on a voluntary basis until a permanent successor has been recruited.

Before that Mr Murrell had worked in the constituency office of former SNP leader and First Minister Alex Salmond.

Mr Murrell married Ms Sturgeon, then SNP depute leader and deputy first minister, in 2010, with Mr Salmond, the then first minister, among the guests.

Mr Murrell is regarded by many as having played a key role in transforming the party's fortunes, helping to modernise SNP operations.

While membership has fallen from the peak of about 125,000 achieved in 2018, to the recently revealed total of 72,186, the party remains the largest and most dominant political force in Scotland.

And with Mr Murrell and Ms Sturgeon at the helm, the SNP has cemented its electoral dominance, having been in power at Holyrood since 2007 and won every election north of the border since then.

However, critics of the SNP under Ms Sturgeon's leadership, both inside and outside the party, long questioned whether it is appropriate to have the key roles of leader and chief executive held by one couple.

Hearings at Holyrood in late 2020 and early 2021 into the handling of harassment allegations made against Mr Salmond saw Mr Murrell's role came under further scrutiny.

At one point he was accused of giving contradictory evidence to the committee investigating the Scottish Government's botched handling of harassment allegations against Mr Salmond.

The inquiry was set up after Mr Salmond won a judicial review against the Scottish Government over its handling of two sexual harassment complaints. The Court of Session ruled that the investigation was unfair and tainted by apparent bias. It awarded him £512,250 in legal costs.  Mr Salmond was later acquitted of separate criminal charges after a trial at the High Court in Edinburgh.

During his evidence to the committee Mr Salmond claimed there was a plot against him which included Mr Murrell, SNP chief operating officer Susan Ruddick, SNP compliance officer Ian McCann, and Ms Sturgeon’s chief of staff, Liz Lloyd.

He cited text messages sent by Mr Murrell which were later obtained by Kenny MacAskill, a former SNP justice secretary who is now an MP in Mr Salmond's Alba Party.

One text from Mr Murrell, on 25 January 2020, said it was a “good time to be pressurising” police as they were “twiddling their thumbs” during an apparent lull in their investigation.

A second said: “The more fronts [Salmond] is having to firefight on the better for all complainers. So [Crown Prosecution Service] action would be a good thing.”

Mr Salmond claimed they had been motivated by the judicial review, which they regarded as calamitous for Ms Sturgeon, and alleged they went on a fishing exercise for police complaints to give impetus to a criminal investigation that started in late 2018.

He said the goal had been to have the police investigation “overtake” the judicial review, allowing the Scottish Government to have it paused, or “sisted”, or to eclipse the loss of the judicial review with his trial.

Mr Murrell rejected Salmond’s claims the texts proved a conspiracy but, in his evidence session acknowledged the language was inappropriate and “out of character.” He said: “To me, that suggests just how upset I was at the time.” During her evidence to the committee Ms Sturgeon said the plot claim was “bizarre”.

In their final report MSPs rejected Mr Salmond’s allegations of unaccepted interference in the police investigation and collusion.
