Within the 27 days since turned SNP chief after which First Minister of Scotland, his celebration's former chief government and treasurer have each been arrested (and launched) in an investigation over lacking cash and hypothesis is mounting that his predecessor might be subsequent. And this was his honeymoon interval.
No surprise Mr Yousaf fled to London to get a change of surroundings and presumably face much less embarrassing questions.
Though the information that adopted him south was the outrage that the SNP bigwig Angus Robertson had been receiving secret funds of £33,000 when he was Westminster chief and had additionally obtained funds for polls which by no means materialised.
One other query mark over what precisely the SNP has been doing with its cash.
However that apart, little doubt the brand new Scottish First Minister thought he would possibly discover a pleasant anti-Tory ally in Labour's London Mayor Sadiq Khan to supply some consolation.
And presumably he was dreaming of the headlines of telling Prime Minister Rishi Sunak he must respect the need of Scotland, no matter that could be.
However as he stood in Portcullis Home on the Parliamentary state he minimize a lonely determine regardless of the entourage round him.
One SNP MP confided that "the percentages of him surviving are very low".
It was maybe not the ringing vote of confidence that Mr Yousaf wanted.
One other Scottish MP from a pro-UK celebration although highlighted how totally different it was to his predecessor Ms Sturgeon.
"You'll by no means have seen Nicola standing round like that.
"When she got here she would all the time go to the [SNP] Westminster chief's workplace and maintain court docket there.
"We by no means even noticed her are available in and even these of us from different events might solely meet her there.
"You actually would not see her loitering round in the course of Portcullis Home.
"She even demanded Theresa Might would go to her within the workplace when she was Prime Minister through the talks.

Yousaf needed to be whisked away.
Do not miss... [REVEAL] [REACT]
There's a assured look concerning the smartly-dressed politician however there's all the time a suspicion amongst MPs it covers an inside insecurity.
Actually the looks of not fairly understanding the place you're going in the course of the parliamentary property is probably not the one that a man floundering within the political waters desires to undertaking.
The chatter is that awaiting on the backbenches is his defeated rival Kate Forbes, not a continuity candidate and in some methods extra divisive together with her well-known spiritual views.
And there was a sure irony in looking for kinship with a Labour politician (Sadiq Khan) on condition that it's Labour that feels poised to exchange the SNP in Scotland.
Given time Yousaf might show the doubters unsuitable, however standing in Westminster yesterday he appeared like a person for whom time is operating out.
