Michael Matheson is set to make a personal statement to the Scottish Parliament on Thursday as questions remain over his £11,000 data roaming bill.

News of the speech came as details of the data charges incurred by the minister during his holiday to Morocco were published by Holyrood.

The EE statement suggests that the minister's £10,935.74 bill was for using roughly 7GB of data between December 28 and January 3. 

The bill does not reveal the websites visited or the apps used.

The breakdown shows Mr Matheson incurred the highest charges on December 28, where 1.26 GB of data cost £2,249.17, and January 2, where 3.89GB of data cost £8666.39.

Mr Matheson has always insisted the costs related “solely to parliamentary and constituency-related work” that he carried out during the trip.

However, there are questions over what amount of work he was doing to use so much of data.

According to EE, sending 175 emails every day for a month would use 2GB.

Using twice that in a day, as he did on January 2, would be more in line with streaming films or TV shows or football matches.

One Tory MSP pointed out that Celtic were playing on the two days with the most data used.

"The 28th Dec and the 2nd Jan, are both notable for significant football matches: Hibs v Celtic and Celtic v Rangers. A coincidence? We need the full truth," Stephen Kerr wrote on X, the site formerly known as Twitter.

The bill was published as Presiding Officer Alison Johnston announced an "urgent review of the Scottish Parliament’s policies on mobile devices and data roaming charges for MSPs."

The review was triggered by the Scottish Parliamentary Corporate Body and will look at "options on disabling sim cards, a mandatory opt-in to data roaming bundles, and personal liability for MSPs where Parliament’s procedures have not been followed."

Ms Johnstone said: "This is an issue which I and the SPCB take very seriously. We must be in a position where we have reviewed and tightened all policies to ensure the present situation cannot happen again.

“The policy review will also set out the circumstances, and cost thresholds, for ‘out of the ordinary’ bills to be escalated to the SPCB for explicit sign off.  This will ensure full transparency and full accountability. It is vital that we have every confidence in the expenses scheme and that its integrity is maintained.”

The Presiding Officer said Mr Matheson had "acknowledged he failed to update his sim card and incurred significant charges" as a result.

Initially, the SNP minister was only going to pay £3,000 towards the cost from his expenses budget, with the Scottish Parliament agreeing to pay the rest.

However, last week, following days of controversy over the whopper of an invoice, Mr Matheson agreed to pay back £10,935.74 in full. 

Asked if the row is distracting the Health Secretary as the NHS faces another challenging winter, First Minister Humza Yousaf told the PA news agency: “Michael isn’t distracted, that is the entire point.”

He said he had spoken to Mr Matheson “at length” during Tuesday’s Cabinet meeting about the NHS.

“It is an issue he is entirely focused on,” Mr Yousaf said.

“For me, the matter is now closed. He has agreed to pay back every single penny of that expense, even though the Parliament wasn’t asking him to do so.”

Mr Yousaf said Mr Matheson had agreed to pay the money back “given the honest mistake he has made in relation to the updating of the sim card”.

The First Minister added: “To me, that is a line drawn under the matter.”

The Scottish Conservatives say there are still questions to answer. Party chairman Craig Hoy said: “The release of Michael Matheson’s data usage while he was sunning himself in Morocco is utterly jaw-dropping.

“It only further highlights the serious questions the SNP health secretary has miserably failed to answer since this scandal first broke.

“The breakdown of charges demonstrates the arrogance of Humza Yousaf in defending his friend and insisting the matter is closed. 

“Speculation will now go into overdrive as to how Michael Matheson racked up this £11,000 roaming bill and whether he was viewing non-political material, particularly on January 2 – a public holiday – when the usage sky-rocketed.

“The only way he will allay the suspicion and rumours is by handing over his iPad so that the browser history can be examined and his claim that the charges were accrued only on parliamentary work can be verified.

“Serious questions remain too for Parliamentary authorities as well when they took Michael Matheson at his word over this eye-watering bill. These charges clearly go against guidelines on expenses delivering best value for money."

He added: "It is in Michael Matheson’s own interest to come clean as to whether or not he was watching high-profile football matches - as has been speculated – on the days when extortionate data charges were recorded.”
