The Scottish National Party's "obsession" with independence has led to "very poor outcomes", Work and Pensions Secretary Mel Stride tells Sky News.
Asked if Humza Yousaf should resign, Mr Stride says "it's a matter for him and the SNP".
He adds: "But it does seem an extraordinary mess that he's managed to get him and the SNP have got themselves into. That they are now potentially going to be beholden to Alba in this situation that they find themselves."
Mr Stride says: "The most important thing for the Scottish people is actually what happens down on the ground with the services that they care about.
"If you look at the SNP's record, their obsession with independence, I'm afraid, has led to very poor outcomes when it's come to health, when it's come to education and a number of other areas, despite the fact that because they're part of the UK, the amount of spending per head in Scotland on public services is about 30% higher than it is in England.
"So overall very unsatisfactory, but it's for them to decide where they go from here."
