THE head of a Police Scotland unit that was the subject of a critical inspector’s report this week has been moved from his post.

Chief Superintendent Clark Cuzen, who led the Counter Corruption Unit (CCU) when it unlawfully spied on journalists’ sources, is now working on a project examining the impact of Brexit on the single force.

Scottish Green MSP John Finnie said: “It’s clear the CCU was out of control and therefore the person in charge must be held accountable.”

The CCU was set up in 2013 as the single point of contact to investigate criminality against police officers.

However, the Sunday Herald newspaper revealed that the CCU had used its spying powers to establish whether serving and retired officers had leaked information to the media about the murder of sex worker Emma Caldwell.

Police forces are required to obtain judicial approval before using the Regulation of Investigatory Powers (Act) for such purposes, but the force failed to do so.

The Scottish Police Authority tasked Her Majesty’s Inspectorate of Constabulary in Scotland (HMICS) with reviewing the circumstances of the breach and the CCU’s wider practices.

During the HMICS probe, other officers came forward to say they had been treated unfairly by the CCU.

On Monday, the Inspectorate published its report and made 39 recommendations for reforming the troubled Unit.

On the CCU’s unlawful molehunt, the report stated: “It is my assessment that the CCU Intelligence development activity lacked objectivity and that those responsible applied prematurely for the acquisition and disclosure of communications data.”

The watchdog added: “I found that information handling processes within the CCU were significantly different from national standards for source and information evaluation and fell below the standards I would have expected.”

It called on the CCU to introduce “robust and effective scrutiny arrangements” for its operations, including “greater oversight” from chief officers.

Derek Penman, the most senior figure at the watchdog, gave evidence to MSPs on Tuesday and he repeated his call for reform.

Cuzen served at the old Strathclyde force before joining Police Scotland in 2013.

He was one of several officers who declined to give oral evidence to the Holyrood Justice Committee on the RIPA breach scandal.

The CCU will now be overseen by assistant chief constable Steve Johnson, while Cuzen is moved to head up a project relating to the European Union.

Scottish Liberal Democrat leader Willie Rennie said: “There are big questions to be answered about why this individual has been moved. It was an unceremonious moment for Police Scotland when individuals refused to give evidence to the Committee and it is only right that we understand what has happened here.”

Finnie said: “A number of officers remain aggrieved by the manner in which they were dealt with by the CCU and all eyes are now on Police Scotland to see if this is the start of changes many believe are needed.”

A Police Scotland spokesman said: "As part of the work ongoing to review the approach to counter corruption in Police Scotland, the operation of the CCU will be overseen by Assistant Chief Constable Steve Johnson working closely with other dedicated senior officers.

“Detective Chief Superintendent Clark Cuzen is currently engaged in work relating to assessing the implications of the EU membership referendum and its potential impact on Police Scotland as part of the wider, European law enforcement community."
