For First Minister Nicola Sturgeon this was a “hiding behind the couch” moment.

Ms Sturgeon must have been praying that she was already ensconced in her luxury retirement apartment in sunny Portugal.

The rest of the SNP establishment and party big beasts – if there were any, really – were left frothing at the mouth after Finance Secretary Kate Forbes dismantled their chosen candidate in the first televised leadership debate.

Ms Forbes, who had dropped a mighty clanger earlier in this contest when she told the world she would have gone by her Wee Free conscience and refused to vote with her SNP colleagues on same sex marriage legislation.

The finance secretary, who is currently on maternity leave from the role, did not hold back as she tore into SNP golden boy health minister Humza Yousaf’s record in government.

The finance secretary, who is currently on maternity leave from the role, came across as being in full agreement with the man they call Hapless Humza and Useless Yousaf.

During a cross-examination of each candidate, Ms Forbes highlighted Mr Yousaf’s failures as a government minister in the health, justice and transport roles. She said: “Humza, you’ve had a number of jobs in government.

“You were a transport minister and the trains were never on time, when you were justice secretary the police were stretched to breaking point, and now as health minister we’ve got record-high waiting times. What makes you think you can do a better job as first minister?”

Ms Forbes had already attempted to distance herself from the current SNP cabinet, despite the fact that she has been holding one of the most senior roles in government since 2020 when she took over the finance job at short notice from Derek Mackay, he of the ferries fiasco.

What Wee Katie did then was to save her most bitter, barbed comment to the end when she was asked if either Mr Yousaf or Ash Regan would get a role in her cabinet if she won.

She responded there was a possibility that Humza Yousaf would, but “maybe not at health” in reference to the chaos he is currently presiding over in NHS Scotland.

About Ash Regan, who appears more poised, confident and forthright by the day, didn’t as much as get a nod in her direction from 32-year-old Cambridge graduate Forbes.

It was a spectacular attack on live TV which left Mr Yousaf’s fans raging and raised the hopes of Ash Regan, and left political commentators on all the channels open-mouthed.

On whether Scotland should keep the monarchy under independence, Ms Forbes said there were “bigger issues facing Scotland”.

She added: “I am pretty relaxed, I would see us as part of the Commonwealth.”

But both Mr Yousaf and Ms Regan declared themselves to be republicans.

Mr Yousaf said he would “keep the monarchy for a period of time” but hoped “an independent Scotland would be a republic in the future”.

Ms Regan said her preference would be to have an elected head of state.

And she said in the “new circumstances” after the death of the Queen last year it might be time for the SNP conference to debate if retaining the monarchy was still the right policy for the party “or whether we should move to a policy of having an elected head of state”.

Swift to put the boot into all three SNP candidates was the Dumbarton MSP Jackie Baillie who is deputy leader of the Scottish Labour Party, who wasn’t slow with the insults either.

Jackie Baillie, left, said: “After 15 years of SNP failure, Scotland is crying out for change.  But all the SNP can offer Scotland is the politically illiterate Ash Regan, the social and economic conservative Kate Forbes and the dangerously incompetent Humza Yousaf.

“Frankly, I would not trust these candidates to run a bath let alone run a country.  While the SNP sinks further into infighting and recriminations, Scottish Labour is facing the future.

“We will deliver the jobs that Scotland needs, end the constitutional wrangling and lock the Tories out of Downing Street.

“Scottish Labour is on the side of the people of Scotland – join us as we deliver the change Scotland needs.”

And many could not believe Ms Forbes decided to go on the offensive by questioning both Mr Yousaf’s own performance and the SNP in general. Nicola Sturgeon’s former office manager Mhairi Hunter was among those to complain.

The one-time Glasgow councillor said: “What the actual f**k is a serving Cabinet Secretary doing using opposition hit lines against a colleague? I did not have this on my bingo card I must say.”

Another former councillor and one-time rising star of the party Rosa Zambonini replied: “What worse is that so many of us worked so hard to get the snp to Government and keep them their. It’s a kick in the balls the hard working staff but more than that the activists”.

SNP policy chief Toni Giugliano, another Sturgeon favourite who failed miserably in his bid to wrest the Dumbarton constituency seat from Labour’s Jackie Baillie, said: “Disagree on policy or strategy by all means – but to undermine your own government, almost pretending you had nothing to do with it, is disgraceful and dishonest. Really poor advice and campaign management (not surprising). They’re about to find out how massively this has backfired.”

His tweet was supported by the likes of transport minister Jenny Gilruth, right,  and John Nicolson MP. And Chris Law MP put his head above the parapet to say: “Trashing our record of government is not reflective on of the successes we have achieved as a party, nor is it going to attract more people to the SNP and independence.  It just looks nasty, short and self serving. Tonight’s debate for two candidates was not their finest hour”.

The debate was a disaster for the SNP, with Scottish Tory leader Douglas Ross saying all three “fought like Nats in a sack”.

Despite them having a wider audience of voters, all three chose to focus on how the party would push for Scexit with major issues like the cost-of-living crisis, health, housing and the economy given either a passing mention or ignored completely.
