FORMER SNP First Minister Humza Yousaf’s decision to ditch the coalition deal with the Greens was “catastrophic,” according to one of its architects today.

In an interview for the Institute for Government (IfG) think tank, Mr Yousaf’s predecessor Nicola Sturgeon, who brokered the coalition deal which brought the Greens into government, slammed his decision.

She said: “I think crashing that agreement was catastrophic and — politics aside — totally the wrong thing to do for stable government.”
