Nicola Sturgeon has been accused of sidelining her cabinet with a series of interventions in different policy areas.
The Scottish Conservatives claimed the first minister was acting “increasingly like a one-women band” while the rest of her ministers had gone into “hiding”.
They said she had made announcements on health, education and policing “without much visible support” from the relevant cabinet secretaries.
On Wednesday Ms Sturgeon used a high-profile speech in London to launch an attack on Westminster austerity by allowing government department spending to rise by 0.5% a year, which she claimed would allow an extra £180billion in spending over four years.
Scottish Tory Jackson Carlaw said: “Nicola Sturgeon is increasingly functioning as a one-woman band.
“The new ministers she appointed have hit the ground hiding, despite the taxpayer now paying for a record number of them.
“In the last fortnight she has been forced to take the lead on education, policing, the economy and health – even sending an emergency team into the Royal Alexandra Hospital when she had previously denied there was any difficulty there.
“On all fronts her government is coming off the rails and, due to her own misjudgements in the ministers she has appointed, she is increasingly having to firefight on every front herself.
“At the same time as her ministers are invisible, she is swanning around London in pursuit of a fantasy agenda to bolster a fantasy status.”
A spokesman for Ms Sturgeon said: “The first minister leads a hugely talented team of ministers who are out and about all the time, speaking to ordinary people. That includes our move to take cabinet meetings to all parts of Scotland, with the latest visit scheduled for Aberdeen next week.
“Perhaps that explains why this SNP governments remains so popular right across Scotland, while the Tories languish in the polls and snipe from the sidelines.”
