Kate Forbes tossed a grenade into the SNP leadership contest by savaging the record of rival Humza Yousaf in Government, but she may have also blown up her own campaign.
Yousaf’s supporters privately admit she had turned her campaign around after a disastrous first week dominated by her opposition to same sex marriage.
But angry party MSPs and MPs believe her excoriating attack on the Health Secretary on live TV, and by implication on Nicola Sturgeon’s Government, have sunk her chances.
