Can Humza save the SNP after treasurer's arrest?

The arrest of the SNP's treasurer Colin Beattie in relation to the probe into the party's finances has overshadowed Humza Yousaf's relaunch speech scheduled for today. Beattie has been taken into custody two weeks after Peter Murrell, the SNP's chief executive, was questioned by police regarding loans made in June 2021. Can Yousaf distance himself from the chaos in his own party? What does this mean for Scottish Labour's chances at the next election?
